I honestly don't know why you'd be a fan of Obama. I mean, I know he came out on gay marriage, which I know you like (To be honest, I don't care nearly as much as you'd think about that. He still supports state's rights to decide on the issue much like I do so it doesn't make a whit of difference to me.)
I've always dislike Obama, and I disliked Mitt since I knew who he was. On Obama's part its nothing super-personal its that his economic plan is going to bankrupt our nation, and he only agrees with the GOP on all of the worst stuff (Patriot Act, foreign intervention, TSA, drug war, the like.) I dislike Romney, similarly, because he agrees with the liberals on all the bad stuff (Obamacare, even if he won't admit it), unfree markets, gun control, the like.
I'm saying 4 < 8 this year but I still don't like Obama at all.
If by "He's great" you mean Ron Paul, absolutely
