Matt Taibbi in Rolling Stone:
It sounds strange to say, but this election season may have done to the word “Republican” what 1972 did for the word “liberal”: turned it into a poisonous sobriquet that no politician with bipartisan aspirations will ever again welcome. The Republicans didn't just break the party — they left it smashed into space dust. They weren't just beaten; the very idea of Republican conservatism was massively rejected in virtually every state where large chunks of the population do not believe in the literal existence of a horned devil, and even in some that do.
They lost in every way imaginable, on every political front. The symbol of their anti-gay crusade, Colorado congresswoman Marilyn Musgrave, was beheaded. The party that had made so much hay running against Mexicans saw noted anti-immigration crusader Bill Sali of Idaho ousted along with several other members of the Immigration Reform Caucus. The GOP's grasp on the so-called “moral values” issue likewise went up in roaring flames, with Rep. Vito Fossella of Staten Island the poster child — his morals were once so perfect that he refused to be seen with his gay sister, and now he's a national joke, bounced after being caught drunk driving and having unprotected, babymaking sex with a married Air Force officer.
