This leads me to think that most undecided voters, almost all who are either Republicans or Independents who support Romney, likely lean to the right, and are currently battling on whether to vote on who they like personally or who they agree with politically. It appears that undecideds should break towards Akin, so I think this race could be close like 2006.
Of course all the undecides are right leaning, for a democrat to be doing well in Missouri, they'd have to pick up some R- leaners. Just because they'd vote for Romney doesn't mean they'll vote for Akin. Akin and Romney are two completely different people, and one of them has yet to completely murder their campaign.
