Regarding the results, you have to remember that unemployment in Iowa is less than 6% right now. In their eyes, the economy is not as bad, so a social Conservative would do well and obviously did.
Romney is just coasting with the Repuklickin Establishment right now, and the Master Neo-Con, John McCain, has surfaced to bestow his blessings on the candy-assed soft-belly. I don't trust the guy. He's held every position on every major issue over the last 20 years.
Huntsman was Obama's China boy-toy... He pretends to be Conservative with his statements, but swings Libertarian. He'll never overcome the Obama appointment, and he'll never be trusted by true Conservatives... He doesn't have a chance, and the polls have always shown that.
Paul is a moonbat. He has a lot of good positions regarding the economy, but he doesn't maintain a reasonable foreign policy. Just imagine a nuclear capable Iran... 'nuff said.
