Politico's David Paul Kuhn

President-elect Barack Obama's 34-point margin of victory with voters under 30 was the largest in a generation, cut across lines of class, color and education — and the most impressive youth mandate in modern American history, according to an exclusive Politico analysis.
Sixty-six percent of voters under age 30 preferred Obama while just 32 percent favored McCain... The youth vote made up 18 percent of the electorate this year, one point more than in the last three presidential elections.
If this analysis is accurate, voters under 30 provided all of Barack Obama's
six-point margin of victory.
