OH-SurveyUSA: Clinton tops most Republicans

[Kaine for Senate '18]

I'd say it breaks down like this:

Romney - 50% chance of winning
Giuliani - 40% chance of winning
Thompson - 6% chance of winning
McCain - 1.5% chance of winning
Huckabee - 0.5% chance of winning

No other candidate stands any notewothy chance of winning the GOP nomination, Ron Paul fanboys' delusions aside.

I'd say Romney does not have a 50% chance of winning.  He is a poor candidate.  Giuliani is the only Republican who can even come close to winning, at this point.
