I think Hynes (Illinois Dem Senate candidate in 2004) will try and oust Rod in Illinois this year.
Hes been attacking him lately publicaly.
The IL Gov has huge problems within his party. I just spoke with a friend very close to the Gov's home neighborhood in Chicago, and the operatives are unhappy and would rather not support him. That being said, it's not clear who wants to take the risk to take him on. Blagojevich has a huge war chest, is very good at raising more, and he's adept at keeping the media from going after him.
