Haslam's got the cash compared to the other candidates, several million bucks in the war chest, the somewhat bizarre method of picking Lt Gov in your state seems to have stamped a bad image on Ramsey I gather, and Wamp apparently wants to secede form the Union or something, so odds favor Haslam versus McWherter and Haslam for the win. McWherter, who would easily pass for a republican in many states, doesn't appear to have the cash or charisma to win unless Haslam produces a tax scandal or something, he's lagging brutally far down in the polls against all three, so ironically his best bet would probably be a mass defection of Dems in the primary to vote the nutjob. Though odds are that would backfire and the loon would get elected
