You might be amazed at how many republicans have started to hate the republican party. Many of these people, such as myself, are supporting RP in a last ditch effort to save the party. Neocons are not conservatives, and they are the ones responsible for what has happened in the last 10 - 20 years, or at least since Reagan's term ended. The US really doesn't have a conservative party anymore. I would almost say the Libertarian party, but some of the stuff they stand for would actually be considered far left wing, it's kind of weird how all that stuff comes together.
Either way, I don't know yet what to think of Huckabee. I'm going to assume that he's just another douchebag, and I'll probably end up voting third party out of spite.
However, Iowa doesn't dictate who will be running, so time will tell I suppose.
