I would enthusiastically support, will support in the primaries, and would actively work for their campaign:
-Palin
-Cain
I would tepidly support, understanding that the country's needs outweigh my preferences, and would actively work for their campaign:
-Pawlenty
-Barbour
-Daniels
-Santorum
-Bolton
I would probably end up disgustedly pulling the lever for:
-Romney
-Newt
-Huckabee
I cannot imagine a circumstance under which I would vote for:
-Trump
-Paul
I would enthusiastically support if they decide to jump in:
-Bachmann
-Rubio
-West
I mostly agree with your assessment. With a couple minor quibbles.
Rubio is such an unknown quantity mainly because he hasn't shown anything (that I'm aware of since elected. Other than to shun the Tea Party Caucus)
Bolton wouldn't put up with any crap. But, I feel he's a little neo-conish.
I would add DeMint as my favorite if he ran.
West sounds good but inexperience would nail him.
Don't know enough about Cain but think I mostly like him. Bothered a little with his ties to the Fed.
Paul the Younger interests me. You could say the same thing I said about West. But, he has a legacy of principles without the baggage.
Now, Palin. I like her. She has more balls than most of the rest of the bunch.
But, she's weak on immigration and has a little neo-con streak in her.
But, I would vote for her and work for her
