Just because you find a way to suck Obama's cock in any and every political thread on these forums when in the end he's just a Democrat that's going to do what the Democrats want him to do. If he doesn't he just wont get anything done at all. It's the curse of a two party system, everything is homogeneous and change is nothing but a talking point.
I'm also not saying that politicians wouldn't change America, I'm saying they can't when they just toe party lines. Independents could bring about real change, sadly they can't get elected - not because people don't like what they stand for - but because they're viewed as stealing votes and having no chance from the start. So in the end Obama as an Independent would be completely believable and hell I'd probably be on the band-wagon, however Obama as a Democrat might as well wear a sign that says "will say what you like to hear for votes". Giving the benefit of the doubt to any of the two major party nominees is just plain naive.
