Ever since McGovern, Democrats repeatedly staked their electoral hopes on an expended avalanch of young voters. This year, it appeared to happen, with Obama winning the votes of 18-29 year olds in a landslide:
Democratic brand domination was the corollary to Obama’s 66%-32% blowout among 18-29 year-old voters. The youth also voted 63%-34% for House Democrats. So, young voters also voted straight ticket for the Democrats down ballot. The real story about the youth vote is not how many “new” voters Obama got to show up, but rather how he produced a gargantuan 34% differential in the youth, versus a 9% margin for Kerry in 2004.
In 2008, 18% of the electorate was comprised of 18-29 year-olds. That figure, when multiplied by the 34 percent differential in Obama voting equals 6.1 points, or a majority of Obama’s popular vote margin. Had the Democratic 18-29 year-old vote stayed the same as 2004’s margin, Obama would have won by about 1 to 2 points, and would not have won 73 electoral votes from Florida, Ohio, North Carolina, or Indiana. “The Electoral College result would not have been the same, nor can we say that Obama would have won the election,” said Greenberg.
Does this overwhelming Obama victory among young voters represent a strong likelihood that the Democrats have a long rule ahead of them?
