Precision targeting is increasingly requisite for all advertising categories, but probably none so critically as political campaigns trying to get out the vote (GOTV).

But with more than half of voters now casting their ballots early or by mail, how do political-campaign teams avoid reaching those who have effectively, already voted?

Thanks to a collaboration unveiled this morning, they can now do that via addressable streaming TV advertising buys.

The new service, dubbed ActiveVoter, is a collaboration of connected TV (CTV) ad-technology platform JamLoop and voter identity platform Aristotle enabling political advertisers -- or for that matter, any brand marketer looking to reach consumers who have not already voted.

While the system cannot actually address individuals who have or have not voted personally, it enables advertisers to exclude ads served to households where someone is known to have already voted, boosting the effective reach and improving the effective CPM of campaigns.

"Suppression occurs at the household level," a spokesperson confirmed, adding that the application isn't always just about targeting a household, but which message to target it with.

"For broader GOTV [get out the vote] messaging, campaigns may choose different creative or broader delivery strategies," she added, noting. The platform provides flexibility."
