Just like how BLOGs powered the 2004 election and social media drove the 2008 election, the 2012 presidential election will be defined by mobile.

EngineYard.com produced the following infographic illustrating how U.S. mobile users have used apps thus far, and the potential with this channel.

Nearly 9 in 10 Americans own a mobile phone, and over 50% of these are smartphones. In response to this there are a handful of states, 1 in 13, that allow online or mobile voter registration. Of U.S. smartphone users, 60% would cast a vote via a mobile app if the option were available.

As for advertising, it’s estimated that $54 Million was spend on election advertising in digital ad platforms, including mobile. For example, Pandora boasts 150 million users, and offers targeting by congressional district or musical genre.

For fundraising, Square has been popular in both the Obama and Romney campaigns, raising $690 Million and $633 Million respectively.
