I'm also not sure that implying 9/11 was responsible for the Iraqi war really flies either. The war in Afganistan, sure.
Then why did we go just the WMDs? I think it played a huge part. It was a target they could easily set their sights on and win to get back some kudos for being asleep at the wheel. I don't you can protect against all kinds of terrorism. But this was a way to unite us and take out a long time foe and reward the military industrial complex. Even if you buy the WMD arguement what threat did they present to us? Iran was and is the much bigger threat to this day and probably sponsored much more terrorism than Saddam.
I don't think it matters who wins. Both parties are devoid of leadership and the political courage it will take to right the ship. When they are more concerned with politics than governing we have a huge problem. This election is most likely going to be close enough that whomever loses will cry foul and be bitter perpetuating the cycle.
I don't get voting for values or principles. I vote for whom I think will lead us best and do the best job. Value voters are not about freedom but getting their values in there for everyone else to have to follow. To some extent I find that very unamerican. If you don't like abortion don't do it. If you want to pray, pray, no one can control your thoughts. But to force these values on others is not something our forefathers would have liked.
