On “Meet The Press” this morning, Tim Russert asked his panel of corresondents whether it was certain Barack Obama will be the Democratic nominee. John Harwood responded yes, then added this qualifier:

There’s nothing Hillary Clinton can do to change it. Stuff could happen to Barack Obama. If we found out that there was a secret poker game when Tony Rezko was paying Barack Obama to write Jeremiah Wright’s sermons and to organize Muslim English professors for a new Weather Underground chapter, maybe Barack Obama could be stopped. But that’s a fantasy and you just simply can’t see it happening.
