Yahoo Taps Offline Data for Political Campaign Ads

A few weeks ago, I wondered why there weren’t more ad products like this.  Now there are:

Through a new pact with the political data/ad company CampaignGrid, Yahoo claims it can target 100 million registered voters, zeroing in on very specific users based on their party affiliation, voting history and even voting frequency, as well as where they live and how old they are. This is exactly the kind of data political campaigns have been built on for decades.
