Uh, we are seeing an enthusiasm gap in fundraising. Obama is out raising Romney with small donors 5 to 1 ($271 million to $58 million), similar to his ratio over McCain in 2008.
Let's be fair: Romney isn't raising much money with small donors because he doesn't need to.
From the news coverage, it appears that he would benefit greatly from that, because it's costing him so much more of this time now to hob-nob with his wealthy supporters and give them the attention they demand while Obama can draw on money from his much broader donor base without detouring from the campaign train.
