I think it's not only that, but a lot of people will probably have had enough Republican government, given what George Bush did to the US - I mean, the economy had never been in such a state, Iraq is a complete disaster ... and just basically the US really needs a huge change, and since Obama promised just that, that's what made him so popular in my opinion. He was almost like a star, kind of a superman who promised to turn everything around. Not to mention his rhetorics... that, compared to John McCain's, are a lot more convincing.
