The Democratic convention has not even begun, and already Barack Obama is in danger of losing it to the Clintons. Patrick Ruffini:

The Clinton chatter is dominant. The Clintons will get two nights in Denver -- Hillary Tuesday, and Bill Wednesday. The coverage on the cables so far this morning has been all about the Clintons. High-profile Clinton surrogates complaining about the lack of VP vetting with the RNC/McCain capitalizing, Bill being upset about his speech topic, Hillary jerking her delegates around, effectively telling them "Nevermind" after making a show about the "catharsis" of the roll call a couple of weeks ago. If the Clintons really wanted to screw with Obama's chances, setting up Hillary 2012, this would be the week to do it. And this is what they seem to be doing.

A lot of this might have been prevented had Obama gone with Clinton for his vice presidential choice rather than Biden. He didn't, of course. And now he's in danger of letting the Clintons turn the story of the convention into the kind of story they like best: one that is all about them.
