It turns out that what hurt the Democrats most of all was disaffection and lack of enthusiasm not among their base but among moderates:
A more direct study of these 2010 no-shows was undertaken by Third Way, a think tank for moderate Democrats, and Lincoln Park Strategies, a Democratic polling firm. They surveyed 1,000 Obama voters who abandoned Democrats in 2010. Half of them were "switchers" who moved their votes to the Republicans this time, while the other half were "droppers" who simply dropped out of the voting this year.This is significant because it shapes how the Democrats will respond to their defeat over the next two years. If it had been the case that their voters stayed home because Congress and the President have not been liberal enough to suit them then we could expect the Democrats to move even further to the left to mollify their base's discontent. Since, however, they've lost the sympathies of moderate voters the party may move more to the center in the next couple of years to try to recapture their lost support among this group.
That survey found that, while the droppers were a bit more liberal than 2010 voters as a whole, they were split in almost precise thirds into liberals, moderates and conservatives. Moreover, just 42% identified themselves as Democrats, while 40% were independents and 8% were Republicans. Almost a quarter of them voted for Republican George W. Bush in 2004.
Nor were the droppers largely minority voters, as the popular stereotype might suggest. Eight in 10 were white, while just 7% were African-American and 5% Latino.
Another reason this is significant is that it bodes ill for the President's reelection chances. Had his base among minorities and young people stayed home it could be assumed it was because he wasn't on the ticket and that they'd probably turn out when he is up again in 2012. The fact, however, that his base did show up and that it was independents who stayed home suggests that Mr. Obama's path to relection is going to be more difficult since it will be harder to woo back disaffected moderates than it would be to rouse his base.
