Clinton could have a chance in Missouri. However, if she campaigns and spends money in Missouri, she could alienate voters who plan on voting for Jason Kander-Senate and Chris Koster-Governor. Roy Blunt already put out ads months ago tying Kander to Clinton.

Yes... but if Clinton is on the climb, how is that bad?
True. McCaskill didn't tie herself to Obama in 2012..she didn't need to. She faced the ultraconservative Todd Akin. Robin Carnahan was probably damaged from Obama's visit in 2010 against Roy Blunt. Kander could campaign with Clinton to mobilize black voters.
