I'd just like to say one thing:
Obama is not a dictator.
He has no direct power over a lot of the things everyone complains to him about. He is president, not president, congress, and senate. He can only do as much as the constitution will let him.
And then there's the previous administrations' problems bleeding over into the now.
Obama is the first black president ever. He was super-duper moderate because he didn't want to screw that up for the rest of all black people. You might not think that means anything, but then you must have never spoken to a real tribal. I think, personally, that if he's reelected he's going to really just go out of his way to say "forget you" to appealing to congress all the time and really fight for the stuff he promised four years ago. I mean, hell, he won't have anything to lose from it.
Oh, and one last thing, Ron Paul is an old hack who is quite possibly the stupidest politician I've ever heard from. His ideas are archaic, his methods are madness, his supporters are handicapped, and his plan is completely unconstitutional (which is delicious irony); he can't change all the things he promised to change without personally replacing all elected officials with people who think his way, which he could never do legally. So fine, go vote for him if you want, he's never going to win ever.
