Which Possible Republican Canidate Has the best Chance against Obama?

[big bad fab]

Crist should have been on the main list and maybe Huntsman too.

I've voted Mitt Romney.
All the others have at least one failure:

Giuliani is the past: he had a chance, he screwed it up. Game over.
Santorum is too conservative and has been fiercely beaten.
Jindal must beef himself up a bit... and is too conservative. And won't be candidate.
Palin is a joke.
Huckabee is too conservative and isn't able to reshape himself: he'll be tired and he'll tire many people in 2012.
Barbour is too old and won't be candidate.
Cantor is too young and too proud of himself. He must smoothen a bit.
Thune is a bit dull and comes from a very small and far away state.
Gingrich is out-of-date and isn't able to sit in the executive branch.
Pawlenty remains not very well-known, but he's the only one to be able to be competitive apart Romney.

Romney may be a flip-flopper but a serious one: a smart guy with a solid family, much money but no dirty money. Lots of experience. Quite in a central position inside the GOP.
Able to lead a campaign. Able not to bend under fierce and personal attacks.

Pawlenty remains not very well-known, but he's the only one to be able to be competitive apart Romney.

Obviously, if he actually won the GOP presidential nomination, he would be plenty well known by November 2012.  Remember, this supposes that the person in question wins the nomination, and then asks about his or her chances in the general election against Obama.

So, take into account only the second half of my sentence.

That was just to say, he would be competitive IF he's the candidate (because he has this "humble" origin image, he 's fine-looking, he has an executive experience, he isn't from the Deep South, he's not a GOP apparatchik). But he won't be.
