FAQs
Q: What are the most effective advertising strategies for political campaigns in the 2026 midterms?
The five proven strategies identified by Comcast Advertising are: use multiscreen TV advertising to build credibility; maintain consistent touchpoints over months; use addressable advertising to reach specific voter segments; expand reach with programmatic TV buying; and work with partners that provide attribution using the same voter data for activation and measurement. These approaches together help campaigns reach voters across screens and optimize where gaps remain.
Q: Why is TV still important for political advertising compared with social media?
TV remains a primary information source for 64% of people and combines sight, sound, and motion to establish credibility and drive engagement. In a survey of about 2,300 people, Comcast Advertising found that viewers were 95% more likely to say political ads feel authentic on TV versus social media.
Q: How long should a campaign run ads to maximize voter reach?
Comcast Advertising found that Top-reaching campaigns stay live for extended periods: 77% run at least three months and 98% at two months or more. Because 27% of voters decide in the final week and 66% decide at least one month before Election Day, keeping messaging live through Election Day helps reach late deciders and those who decide earlier.
Q: How does addressable advertising help reach specific voter groups?
Addressable, data-first strategies reach unexposed, underexposed, and swing voters on streaming or traditional TV by targeting households precisely. Analysis shows one in three target households were reachable only through addressable TV, and 41% of swing voter reach in a recent campaign was unique to addressable.
Q: What is programmatic TV buying and how can it expand reach?
Programmatic is an automated, data-driven approach to buying TV that fills inventory gaps and boosts incremental reach. In one campaign, shifting just 5% of media budget to programmatic streaming drove a 12.5% incremental reach and allowed the campaign to reach 11% of total campaign households with minimal spend.
Q: How can campaigns get accurate attribution for who they reached?
Accurate attribution requires using the same voter data for both activation and measurement so targeting and measurement align to a consistent household identity. Building an audience once and activating it across channels eliminates guesswork, enables unified targeting, and produces cleaner measurement to identify remaining gaps.
Q: What should we look for when choosing a media partner for a political campaign?
Choose partners that enable consistent household identity for both activation and measurement, can activate audiences across channels, and provide clear attribution without guesswork.
Q: If I have a limited budget, can small shifts to programmatic really make a difference?
Yes — the content shows that shifting just 5% of a media budget to programmatic streaming produced a 12.5% incremental reach in one campaign and reached 11% of total campaign households with minimal spend, demonstrating meaningful incremental gains from small reallocations.
