DNC Smells Blood With McCain House Gaffe

The DNC is keeping the heat on John McCain over his admission that he didn't know how many houses he owns. The committee is hosting a news conference Friday morning outside the Senator's Arlington condo, shooting out a media advisory that reads: "McCain lives at 'most enviable address in Virginia,' while middle-class families face economic downturn."

Meanwhile, aides to the DNC walked Washington D.C. to create a man-on-the-street video, asking interviewees if they can remember how many houses they own.

Clearly Democrats, including the Obama campaign, smell blood and are going to milk the McCain gaffe for all its worth. It's hard to see, however, how this goes on longer than today. On Saturday, Obama is set to trot out his vice presidential nominee and then on Monday the Democratic convention begins.

McCain, meanwhile, now stands to lose more than a week's worth of news cycles. It will be telling to see just how this dynamic is reflected in the post-convention polls.
