The Times says that Obama's fundraising machine may not be all it was cracked up to be. The story is maddeningly anecdotal and buries the most significant piece of evidence in the back:
The Obama campaign set a goal in mid-June of raising $300 million for the campaign and about $150 million for the Democratic Party over four-and-a-half months, fund-raisers said. As of the end of July, however, the Obama campaign was well short of the $100 million a month pace it had set, taking in about $77 million between the campaign and the party that month.
More than any national poll, the money question would concern me. This story looks like a warning, but I don't know if there's much more to take from it then that.
