Political advertisers evaluating platforms for the 2026 midterms should prioritize six capabilities: omnichannel activation across CTV, programmatic, audio, social, and search; CTV inventory access with pre-negotiated deals; geopolitical targeting at the congressional district and state legislative level; rapid activation workflows that compress planning-to-launch timelines; built-in compliance and brand safety tools; and AI-powered planning and optimization that preserves human strategic control.
Political ad spending for the 2026 midterms is projected to reach $10.8 billion, making this the most expensive midterm cycle in US history. That total represents a 20%-plus increase over the 2022 midterms and comes within striking distance of the $11.2 billion spent during the 2024 presidential cycle.
The forces driving that spending are significant. Control of both chambers of Congress is up for grabs. A record wave of congressional retirements is creating open-seat races where neither candidate enters with the advantages of incumbency. Redistricting is underway in several key states, including California, Missouri, North Carolina, Ohio, Texas, and Utah. With more competitive races, more open seats, and more uncertainty than any recent midterm, campaigns that cannot move quickly from planning to activation risk falling behind before the general election even begins.
For political advertisers managing campaigns across CTV, programmatic display, streaming audio, social, and search, the platform you choose determines whether your team can move at the speed this cycle demands or gets buried in manual execution during the final sprint. This guide covers what political advertisers should prioritize when evaluating advertising platforms for the 2026 midterms.
Key Takeaways
Political advertising operates under constraints that intensify every platform decision. The timeline is fixed, as Election Day does not move. The spending cadence is compressed: Basis data from the 2024 election cycle shows 48% of digital ad budgets ran in the final 30 days, with nearly half of that concentrated in the last 10 days. As such, the margin for error is narrow. A pacing miscalculation or delayed campaign launch in late October cannot be corrected in November.
These constraints shape the platform evaluation criteria that follow. Each section addresses a capability that matters in any advertising context but becomes especially high-stakes when the deadline is immovable, the budget is front-loaded, and there is no second attempt.
Political advertising in 2026 spans a wide channel list. CTV is projected to account for 23% of total political ad spend, the only channel forecast to experience growth during this cycle. Streaming audio is emerging as a breakout opportunity, reaching voters during screen-free moments that CTV and display miss entirely. Social platforms remain essential for fundraising and persuasion. And programmatic display and video continue to serve awareness and retargeting roles across the funnel.
The operational question is whether your platform can activate across all of these channels from a single workflow or whether your team needs to rebuild campaigns in separate interfaces for each.
Platforms that handle programmatic, direct publisher buying, search, social, and CTV in one system eliminate the manual handoffs that slow campaign launches and create inconsistency across channels.
For political campaigns specifically, channel coverage should include access to CTV inventory across platforms that accept political ads (Hulu, ESPN, Roku, YouTube, DIRECTV), programmatic audio through streaming and podcast platforms, and social activation through Meta, Google, TikTok, and Snapchat. Platforms that also support programmatic terrestrial radio through partnerships like iHeart expand reach into a format that political advertisers have historically underinvested in. Digital out-of-home (DOOH) is another channel worth evaluating, particularly for reaching voters in transit, at events, and in public spaces where screen-based media doesn't reach.
What to ask:
The spending cadence of political advertising creates unique operational demands. Basis data from the 2024 election found that 48% of digital ad budgets ran in the final 30 days, with nearly half of that concentrated in the last 10 days.
That compression means platforms need to support rapid campaign activation, real-time budget pacing, and mid-flight optimization under sustained time pressure.
Specific capabilities to evaluate:
Political targeting operates under platform-specific restrictions and state-by-state regulatory variations. Restrictions on audience targeting for election ads on platforms like Google and Meta, combined with state-by-state regulatory variations, make audience strategy a jurisdiction-specific exercise.
Geopolitical targeting has become an increasingly important tool in this environment. Basis data from the 2022 midterms showed that nearly 20% of political programmatic ads used geopolitical targeting, with 51% targeting by congressional district and 32% by state senate district. With redistricting underway in multiple states, the ability to target by updated district boundaries is essential.
Beyond geography, platforms should support integrations with major voter data providers, including L2, TargetSmart, i360, Tunnl, and Aristotle. Direct integrations with identity resolution providers like LiveRamp allow campaigns to upload, match, and activate voter file data quickly rather than waiting days for manual onboarding. Platforms with additional data partnerships—such as Foursquare for location intelligence, CivicScience for attitudinal data, and Adastra for identity resolution—give campaigns more options for building precise audience segments.
Automatic Content Recognition (ACR) data from smart TV manufacturers adds another layer of targeting precision. Campaigns can reach households based on actual viewing behavior, not inferred demographic proxies, and serve political messages in contextually appropriate streaming environments. Cross-device and household-level targeting further extends this capability, allowing campaigns to expand reach beyond individual devices to entire households.
What to ask:
CTV is the only media channel projected to see increased political spending over the 2024 presidential cycle, with $2.5 billion in CTV political ad spend expected in 2026. For political advertisers, CTV access is as much about securing inventory at favorable pricing as it is about reach: CPMs surge as Election Day approaches, and campaigns that wait until October pay a steep premium.
The CTV inventory ecosystem for political advertising has expanded significantly. Disney has opened inventory across Hulu and ESPN. OEM platforms from LG, Samsung, and Vizio operate their own FAST channels with growing political inventory. DIRECTV, HBO Max, Paramount, and other premium providers are accepting political and advocacy advertising in increasing volumes. Peacock, Tubi, Sling, Discovery+, Pluto TV, and fuboTV have also entered the political CTV market, giving campaigns a broader set of inventory sources than any previous cycle.
But not all CTV inventory is created equal. Platforms that accept political ads (Hulu, Roku, YouTube, ESPN) will see the sharpest CPM increases as Election Day approaches. Basis data from 2024 showed that programmatic video CPMs nearly doubled the election cycle average in November and had already increased 50%+ above average in October.
The platform evaluation question is whether your advertising platform gives you the inventory relationships and buying mechanisms to lock in favorable pricing before that surge hits.
Buying mechanisms to evaluate:
Measurement capabilities matter here too. Platforms that integrate cross-channel reach measurement—comparing digital campaign performance to linear TV—help campaigns quantify incremental reach and optimize budget allocation between CTV and traditional broadcast. Basis integrates Comscore Campaign Ratings for Advanced Reach Measurement, enabling campaigns to measure cross-channel reach, frequency, and incrementality from a single platform.
Live sports inventory deserves special attention in 2026. The FIFA World Cup (June-July), NFL, and college football season overlap directly with general election spending. Political advertisers increasingly use live sports as a targeting proxy, reaching voters in specific states and DMAs based on the games they watch. Platforms with strong sports-adjacent CTV inventory access will have a meaningful advantage. BasisTV+ provides access to CTV/OTT, addressable, and live sports and events inventory, reaching 93% of US smart TV households with 1,000+ advanced TV targeting parameters and 80+ trackable metrics.
AI-generated political content, including deepfakes, adds a new layer of brand safety complexity in 2026. Deepfake political ads are already running in midterm campaigns. There is no federal law governing AI use in political advertising, and while 26 states have enacted some form of deepfake disclosure legislation, enforcement remains limited.
At the same time, platform policies around AI disclosure are evolving quickly. Google requires political advertisers to disclose any use of AI in their ads. Meta requires disclosure in certain circumstances. The directional trend points toward greater transparency requirements.
Political advertisers need platforms that build compliance into the workflow rather than bolting it on as a separate step. Specific capabilities to look for:
Political advertising clients range from well-funded Senate campaigns with experienced media buyers to first-time candidates and ballot measure committees running their first digital campaign. The platform should accommodate both.
For experienced political media teams, self-serve access with full control over targeting, bidding, and optimization is essential. For campaigns that need additional support, managed service options that handle execution while preserving strategic control offer a middle ground.
The Basis Candidates & Causes practice has served political advertisers for two decades, offering service tiers from fully self-serve to fully managed execution. The team includes more than 40 political subject matter experts who understand the compliance, timing, and operational nuances that distinguish political media buying from commercial campaigns. In the 2024 cycle, the team supported more than 1,400 state and local campaigns, managing over $130 million in political ad spend across video, display, native, audio, and text ads.
This flexibility matters because political campaigns don't all operate the same way. A statewide Senate race and a state legislative campaign have very different team structures, budgets, and execution needs. The right platform adapts to those differences rather than forcing a one-size-fits-all approach.
Audio represented just 3% of political ad spend during the 2024 election season, despite the average voter spending 21.2% of their total media time consuming audio content. That gap is a meaningful opportunity for political campaigns willing to move early.
Streaming audio reaches voters in screen-free moments: during commutes, workouts, and household tasks. With workers returning to offices and commutes increasing, audio consumption is rising. Podcast listenership has demonstrated increasing resonance across key voter demographics. And with programmatic buying now available even for broadcast radio inventory, the barriers that once made audio difficult to activate at scale have been largely removed.
Campaigns that are early movers in streaming audio stand to benefit from lower CPMs and less competitive inventory than they will find in CTV, particularly during the October-November sprint when CTV pricing spikes.
Platforms should support programmatic audio activation through streaming services like Spotify and iHeart, ideally within the same workflow used for CTV, display, and social. Campaigns that can add audio to their channel mix without logging into a separate tool or rebuilding targeting from scratch will capture this opportunity more efficiently. Exclusive inventory partnerships add further value. Basis provides access to DAX (Digital Ad Exchange) inventory reaching over 20% of total US audio consumers across leading streaming and podcast platforms, with 60,000+ podcasts and 350+ terrestrial US radio stations, plus a multicultural network for reaching Spanish-speaking voters.
The operational demands of political advertising compress the workflow challenges agencies already know well into a much shorter timeline. Basis data shows that agencies using its automation platform save an average of 51 hours per campaign—equivalent to roughly 6.5 work days—and approximately $8,925 per campaign in efficiency gains. In political advertising, where the window for peak spending narrows to weeks, those saved hours translate directly into competitive advantage.
Automation delivers measurable time savings across five areas that consistently drain political campaign time:
Campaign setup and trafficking. Building campaigns across CTV, display, audio, social, and search typically requires logging into separate platforms and manually configuring each. Automated platforms let planners build campaigns once and traffic them to all channels simultaneously, eliminating redundant data entry and the consistency errors that come from rebuilding campaigns in interfaces that were never designed to talk to each other.
Budget pacing. When 48% of your budget runs in the final 30 days, real-time pacing visibility isn't a convenience feature — it's a necessity. Automated pacing tracks spend across all channels from a single view and adjusts delivery rates to hit flight date targets without daily manual check-ins across disconnected tools.
Performance monitoring. Cross-channel dashboards that consolidate CTV, display, audio, social, and search metrics into a single view let teams identify optimization opportunities faster. In the final sprint, the ability to spot an underperforming tactic and reallocate budget in hours rather than days can determine whether you reach persuadable voters before Election Day.
Reporting. Pulling final reporting from multiple platforms and consolidating it into client-ready formats is one of the most time-consuming tasks in the campaign lifecycle. Automated reporting with customizable templates eliminates manual exports and spreadsheet merging.
Billing reconciliation. Managing billing across multiple delivery sources creates additional operational burden, particularly for campaigns with FEC reporting requirements. Platforms with billing integrations and automated reconciliation streamline a task that otherwise consumes hours per campaign.
AI adds measurable value to political advertising in two areas: pre-activation planning and campaign optimization.
On the optimization side, AI-powered bidding can process far more data signals than any human media buyer, adjusting bids and allocations in near-real-time based on performance data. For campaigns running CTV, audio, display, and social simultaneously, automated optimization improves performance without requiring additional headcount. Basis' SmartBid technology processes dozens of performance signals throughout the day to make continuous, goal-aligned adjustments across the full media mix. In testing, SmartBid has delivered a 133% increase in return on ad spend (ROAS).
On the planning side, tools like Compass by Basis represent a shift in how campaigns can approach pre-activation workflows. Compass generates media strategies by synthesizing uploaded campaign briefs, analyzing market data, and utilizing Basis' proprietary omnichannel IMPACT framework. The output includes a proposed media strategy, channel mix recommendations, targeting recommendations with named audience personas, and a presentation deck. Agency teams can then refine the strategy through a back-and-forth conversation with the Compass agent before plans flow directly into campaign activation. Every recommendation includes clear reasoning, so teams can see what's driving each allocation and adjust the strategy as needed.
For political advertisers managing multiple races simultaneously, or for consultancies handling campaigns across several states, this kind of planning acceleration can be the difference between launching on time and falling behind.
That said, AI should augment strategic judgment, not replace it. The strongest platforms automate mechanical tasks and surface recommendations while preserving full human control over strategic decisions. Political campaigns that differentiate through audience insight, creative strategy, and local market expertise need platforms that enhance those capabilities rather than attempting to automate them away.
The following checklist summarizes the platform capabilities political advertisers should evaluate for the 2026 midterm cycle.
Channel coverage. Does the platform support CTV, programmatic display and video, streaming audio, DOOH, social (Meta, Google, TikTok, Snapchat), search, and direct publisher buying from a single workflow?
CTV inventory access. Which premium publishers are accessible? How many PMPs are pre-approved for political? Does the platform support programmatic guaranteed buying? Does it offer cross-channel reach measurement against linear TV?
Political targeting. Does the platform support congressional district, state legislative district, DMA, and hyperlocal targeting? Which voter data providers integrate directly? How fast is voter file activation? Does the platform support cross-device and household-level targeting?
Activation speed. Can the platform move from brief to live campaign across channels in hours? Does planning connect directly to activation without manual reformatting?
Pacing and optimization. Does the platform provide real-time cross-channel pacing? Can budget be shifted between channels mid-flight from a single interface? Does the platform offer AI-powered bidding that optimizes across the full media mix?
Brand safety and compliance. Does the platform include DAA Political Ad Icon support, rapid creative review, contextual controls, and verification partner integrations? Does it include fraud prevention tools?
Streaming audio. Does the platform support programmatic audio alongside CTV and display within the same workflow?
AI capabilities. Does the platform offer AI-powered optimization and planning tools? Do those tools preserve human control over strategic decisions? Do AI recommendations include transparent reasoning?
Service flexibility. Can the platform scale from self-serve to fully managed execution based on campaign needs?
Political expertise. Does the platform provider have a dedicated political advertising practice with experience across election cycles?
Basis has served political advertisers for two decades, supporting thousands of campaigns, independent expenditure committees, and issue advocacy advertisers since 2006. In the 2024 cycle alone, the Candidates & Causes team supported more than 1,400 state and local campaigns, managing over $130 million in political ad spend. The platform aligns with the evaluation criteria outlined above:
The 2026 midterms will test every political advertiser's ability to move fast, spend efficiently, and reach the right voters across a fragmented media environment. The platform you choose determines whether your team spends the final 30 days executing strategy or wrestling with disconnected tools.
What makes political advertising platform requirements different from commercial media buying?
Political advertising operates on a fixed deadline with no flexibility. Election Day does not move, and the spending cadence compresses heavily into the final weeks. Platforms need to support rapid activation, real-time pacing under extreme time pressure, political-specific targeting (congressional districts, voter file data), compliance tools for political ad disclosure, and inventory relationships with publishers that accept political advertising.
How early should political campaigns lock in CTV inventory?
Early—ideally before September. Programmatic video CPMs in 2024 nearly doubled the election cycle average in November and increased 50%+ in October. Campaigns that secure PMP deals and programmatic guaranteed pricing before September will have a significant cost advantage over those relying solely on open exchange buying during peak season.
Can smaller campaigns benefit from the same platforms used by major races?
Yes. Platforms with flexible service tiers accommodate campaigns at different scales. Self-serve access gives experienced political media buyers full control, while managed service options support campaigns with smaller teams or less programmatic experience. The operational efficiency gains from automation — faster campaign setup, unified reporting, automated pacing — benefit campaigns regardless of budget size.
How should political advertisers think about streaming audio in their media mix?
Audio represented just 3% of political ad spend in 2024 despite voters spending over 21% of their media time with audio content. That gap means lower CPMs and less competitive inventory compared to CTV, particularly during the October-November sprint. Campaigns that activate streaming audio through the same platform used for CTV and display can add the channel without additional operational overhead.
What role does AI play in political advertising platforms?
AI delivers value in two areas: campaign optimization (automated bidding, pacing, and budget allocation based on real-time performance data) and pre-activation planning (generating media strategies and channel mix recommendations from campaign briefs). The strongest platforms use AI to accelerate mechanical tasks while preserving human control over strategic decisions like audience definition, budget allocation, and creative messaging.
What is geopolitical targeting in political advertising?
Geopolitical targeting allows political advertisers to serve ads based on political boundaries—congressional districts, state legislative districts, DMAs, ZIP codes, and other jurisdiction-level geographies—rather than relying solely on demographic or behavioral audience segments. This capability is especially important during redistricting cycles, when district boundaries shift and campaigns need to reach voters within updated lines. During the 2022 midterms, Basis data showed that nearly 20% of political programmatic ads used geopolitical targeting, with 51% of those targeting by congressional district and 32% by state senate district. For the 2026 cycle, with redistricting underway in states including California, Missouri, North Carolina, Ohio, Texas, and Utah, platforms that support targeting by updated district boundaries give campaigns a structural advantage in reaching the right voters.
How do political advertisers measure CTV performance against linear TV?
Cross-channel reach measurement tools allow campaigns to compare digital and CTV performance against linear TV, quantifying incremental reach, co-viewing lift, and frequency differences. In one statewide campaign measured through Basis' integration with Comscore Campaign Ratings, digital channels delivered 4.5 million incremental viewers who were unreachable through linear TV alone, with CTV delivering 5x lower ad frequency than linear and a 44% lift from CTV co-viewing. These metrics help campaigns optimize budget allocation between CTV and traditional broadcast based on actual reach data rather than estimates.
