I'm about in the same boat, but I kind of rank them in this order.

1. Ron Paul
2. Newt Gingrich
3. Mitt Romney
4. Rick Santorum

I think that the financial part is the biggest issue right now, and the country is due for a military build-down like we've had at the end of previous wars, and Ron Paul's about the only one that will do both of those. His foreign policy? Not great, but secondary for me at this very moment.

Newt? He's a terrible candidate, but at least he can make a point in a debate and might be able to win over minds to our side. 

Romney would be the second coming of McCain and would give us results much like Bush's first 6 years, culminating in a repeat of the 2006 election... Only I think the republican party would have an even harder time recovering this time.

Santorum... is Nehemiah Scudder. He'd definitely lose though because he'd successfully push the moderates away.

I think if Santorum is the nominee, I'll vote Libertarian. If Romney is, I'll reserve my judgement based on his running mate. Otherwise I'll probably go ahead and vote for Paul and Gingrich, even though Newt doesn't deserve my vote.

I think Mitt entered with this belief that he was next in line and inevitable. In many of the debates he seemed like he was just trying to run out the clock. He might have nothing to worry about though as he seems to be the best the GOP has in the race at this point. I really wish Mitch Daniels were in it. It just doesn't seem like the GOP is all that serious about the '12 election at all even though Obama is quite vulnerable and has failed on virtually every issue.
