Radio Can Boost Voter Reach And Ad Efficiency.

Political campaigns can expand voter reach and reinforce messaging by combining broadcast radio, streaming audio, podcasts and connected TV (CTV), according to iHeartMedia, which says a coordinated approach helps candidates and causes connect with voters throughout their daily routines.

iHeartMedia says that campaigns should plan around the moments when voters consume media rather than treating each platform as a separate channel. Voters may listen to local radio in the morning, stream audio during the workday, hear podcasts during commutes and watch CTV at home in the evening.

Broadcast radio provides mass local reach through news, sports, personalities and community-focused programming. Streaming audio extends campaigns’ presence beyond traditional radio listening, while podcasts offer opportunities to reach audiences who actively choose content aligned with their interests. CTV adds visual storytelling that can reinforce messages voters have already heard through audio.

The combination can help campaigns build both reach and frequency, two important elements of political persuasion and voter mobilization. Repeated exposure can help reinforce campaign themes, while using multiple platforms can introduce messages to voters who might otherwise be missed by a strategy concentrated in one medium.

iHeartMedia points to a Nielsen Media Impact analysis across nine markets that examined shifting media spending from television to radio. According to the company, the analysis found that reallocating incremental media weight from television to radio expanded registered-voter reach to as much as 62% and swing-voter reach to as much as 69%. The analysis also found radio delivered 25% to 31% greater cost efficiency than adding more television weight alone.

The findings highlight the potential value of audio for campaigns working with limited budgets and facing a crowded election-season advertising market, although results can vary by market and campaign.

iHeartMedia recommends that campaigns coordinate broadcast radio, streaming audio, podcasts and CTV around specific voter objectives. Audio can help extend reach among priority audiences and maintain a presence across daily listening occasions, while local news, talk, sports and community programming provide context for campaign messages. CTV and other video placements can reinforce those themes through visual storytelling.

A cross-platform plan can also help campaigns manage frequency across different media environments rather than relying on additional spending in a single channel that may repeatedly reach the same voters.
