Oregon is another place where anti-war Nader voters would draw away a lot of Gore support, I think.
Except a Gore led war would be more popular than a Bush led war, because Gore would handle it better. Thus, there wouldn't be as many anti-war supporters.
Where do you get this prediction from?
Gore would have gone in with more international support, meaning the Iraqi's wouldn't be as violent against the "coalition" because it would have had more credibility. Thus, the war would be recieved better since there would be less casualties.
That is an assumption with no basis in reality. The only way Gore gets more international support is to allow France and Russia to keep their sweetheart oil deals after the war, which would lower the popularity at home. Buying votes at the UN would be a policy disaster for Gore, and the French were not coming along without it.
