Sorry Genseneca, 2012 will almost certainly be different. Remember how the Tea Party ousted RINO Mike Castle in the delaware primary? It was worth it even though a democrat won the seat, because people of the conservative stripe are not going to play the game any more of a RINO is better than the democrat. If it's a choice between a democrat who doesn't pretend to be anything than what he is, and a RINO pretending to be a conservative, I'll take the former. RINOs are really the ass-end of the american polity, even worse than "moderates". Even worse than white women voters.
If the country will vote obozo another term against a conservative GOP candidate, after all that has happened, then it means the country has become utterly irrational, and all reasonable people will abandon the political process and just focus on other means of looking out for their interests as the country slides down the abyss. Particularly in a second term, obozo will abandon all pretense of being "moderate" since he then has nothing to lose, and focus on the worst elements of his leftwing agenda.
But I don't believe Romney has a chance, even if he does have the corrupt RINO establishment backing him.
