Political advertisements go mobile for 2012 elections

Geo-targeted mobile advertising, which made its debut among political campaigns during the 2010 midterms but is just now becoming more widespread, offers presidential campaigns an attention-getting new way to stalk voters wherever they may be found — the state fair, the ballgame or the caucus site. On the presidential level, this means targeting ads at primary- and caucus-goers in the days leading up to the election — or even as they’re heading to the polls on Election Day.
