Iowa was one of the key swing states in both 2000 and 2004 and this seems likely to continue in 2008.
President: Bush lost Iowa narrowly in 2000 and won it narrowly in 2004. I was somewhat surprised given the strong anti war tradition in the state but the GOP got a strong turnout with Christian conservatives. This year however I think the anti war and anti Republican sentiment will tip the state back to the Democrats
