The Iraq War Trigger Event: 9/11 Attack Confirming Event: Obama's Election
A large part of the appeal of Obama is his message and style which is more distinctly anti-Bush than Clinton or McCain. Bush's low public approval (nationally and internationally) create a public mood for something much different and a greater tolerance for a candidate who has been on the national scene for a shorter period of time.
That might be. The only observation I have is that the five years from the start of the Iraq War (2003) to the 2008 election runs a little bit on the high side. The average time between "trigger" event and "confirmation" is three years. But time will tell. One thing is for certain: historians 20 to 40 years from now will be doing a lot of interesting analysis of the times in which we now live.
