They don't exactly lie. When you run from president you do not know all the facts there are to know when making your campain. Some details are only for the president to know, so once elected he finds out all this crap that may slow down or throw off his plans that he did have while running.
I'd vote Obama. He essentially did do everything he said he would or at least tried. Troops are coming home. What's his face is dead. We are slowly focusing on our own problems while keeping the middle east in the corner of our eyes. I see no problem with Obama. He is doing his best and I feel it is better to let him continue on this steady rate we are going than changing people and having to essentially start all over again.
Plus Mitt blaintly lies in his campain and doesn't admit to it when caught. You know damn well he will lie to you as president with a smile on his face.
