I'm pretty sure that the establishment will - actually, most of it already has - rally around Mitt Romney. There will be a few defectors that support Pawlenty, or other candidates, but Romney will definitely be the "establishment" candidate. Palin will have to rely on Tea Party support and people who owe her favors.
Middle-aged, inoffensive, calm, mid-western Man.
That's my biggest fear...
Mitch Daniels, luckily for you, probably won't be nominated due to his controversial statements regarding a national sales tax and a social truce and what not. Not that I think he automatically would be a good candidate, since he may turn off conservatives in exchange for independents.
Unless you are talking about Pawlenty, who is also a mid-western man.
