The other telltale sign of Obama’s failure was the youth vote. Democratic victories in 2006 and 2008 very much depended upon increased support from and turnout among young voters. In 2008, Obama’s organization specifically targeted these voters. In this election, voters 18 to 29 again favored Democrats by a whopping 56 to 40 percent in House races. But they constituted only 11 percent of the electorate this year compared to 18 percent in 2008 House races and 12.5 percent in 2006. Obama and his political aides recognized that this was a problem, and in the last weeks of the election, tried to rouse these voters (hence all those campus rallies and the “Daily Show” appearance). But it was too late.The natural comparison here seems to be with 2006 and the drop doesn't seem that big, particularly given anti-war issue (something that, even without the draft, would tend to skew by age) four years ago.
