Election 2012 - voting demographics information

Youth Vote
Obama enjoyed a wave of youth support in his run to the presidency, winning 66 percent of voters aged 18-to-29 in the race against Republican Senator John McCain. Twenty-two million young voters cast ballots, making up about 18 percent of the electorate -- two million more than in 2004, according to exit polls and the Center for Information and Research on Civic Learning and Engagement. Today that passion has cooled amid gridlock and partisanship in Washington and a surge in unemployment that is souring young voters.
