This interview with Mike Huckabee [1] has some interesting insight into the opposition's troubles. Especially this part:

Republicans need to be Republicans. The greatest threat to classic Republicanism is not liberalism; it's this new brand of libertarianism, which is social liberalism and economic conservatism, but it's a heartless, callous, soulless type of economic conservatism because it says "look, we want to cut taxes and eliminate government. If it means that elderly people don't get their Medicare drugs, so be it. If it means little kids go without education and healthcare, so be it." Well, that might be a quote pure economic conservative message, but it's not an American message. It doesn't fly. People aren't going to buy that, because that's not the way we are as a people.

Too bad the GOP establishment will write this off as a bunch of sour grapes nonsense. Read the whole thing, especially the part about Democrats running to the right. He's basically endorsing moderate Democrats as the new Republicans. Is he angling for the #2 spot on either ticket?
