"Gingrich won by being mean... His win is based on that. And the SC Republicans (and a large part of the Republican base) want mean."
That's it. The Republican "base" is tired of having people suggest that race hatred and greed are less than honorable characteristics, and they are angry about it. So they are ready to openly abandon any pretense that they give a damn about all of their religious cant and family values hooey, and get in line behind the meanest motherfucker they can find, even if he is an openly corrupt, grossly immoral son of a bitch who would steal his granny's coffin if it made him a nickel (and probably marry her too, if he thought it would advance his political career,) and who makes fools of them every time he opens his mouth and utters another preposterous lie.
Well, at least here in South Carolina, the first State to go to war to defend the high principle that, if you have enough money, you should be able to own people with less money. They've got quite a record here of siding with the lowest bastards they can find.
So, maybe Mitt went to sleep last night counting on the Republican "base" in the rest of the country being just a tiny bit less a pack of vicious, self-serving animals than they are here. Well, Mitt, as far as I can tell, this sort of thing is as catching as the Ebola virus among Conservatives, so don't hold your breath waiting for that. And here, we thought the 2012 election was going to be between the sane and the crazy. We didn't realize that things in this country have already gotten so bad that people are going to have the chance to choose between a human being and a mad dog.
