I think alot of folks don’t believe Romney is a conservative but they do believe he is the only one that can beat Obama. (My very conservative father being one)
Unfortunately one belief is as misguided as the other.
Romney is not a conservative, and you can’t possibly point to a substantial difference between he and Obama except their motivation.
