Well, Duh

Forget the Kool-Aid: Obama's Support is Real
Obama, meanwhile, seems to be appealing to what might be called the new "silent majority." Sure, he's got his share of stage-rushers and Kool-Aid drinkers, but he's also appealed to millions of casual voters—the ones who don't go to his rallies, don't donate to his campaign, but do show up on primary day and check his name off on the ballot.
…
But the real problem with sneering at the fervor that Obama has stirred is that it ignores how elections are won and how governing coalitions are built. The truth is that even voters who aren't moved by Obama's substantive appeal are still, by and large, favorably impressed by him and willing to at least consider voting for him.
…
Hillary Clinton, by contrast, calls to mind Walter Mondale, who in 1984 combated Reagan's sunny vision with what Newsweek described as "a gigantic To-Do List, a leaden compendium of programs heaped one on another … as if he intended to crush his audiences in specifics."

Democrats have enjoyed simultaneous control of the White House and both houses of Congress for a grand total of two years since Jimmy Carter was voted out. Now, presented with a candidate who is inspiring record turnout and demonstrating broad appeal in some of the most Republican parts of the country, you'd think the excesses of a relatively small percentage his supporters would be the least of their concerns.
