I think you are pretty much correct on your analysis of the situation. Personally I prefer Newt in the remaining 4, but will vote for the nominee in general no matter who. I could not live with myself if I gave the Chicago community organizer any benefit whatsoever.
Newt and Santorum are both fine with me, but I’m going to pull the GOP level no matter what. No matter how bad Romney is (and I know he’s bad), he’s nowhere near as bad as Obama.
Romney may be a dishonest, weaselly, unprincipled politician, but at least he’s not a flagrantly corrupt socialist like Obama.
