I don't have a lot to add on it. I thought that both candidates agreed on a number of topics; However, McCain's voting record seriously hampered his ability to be convincing or credible.
The only other thing that was sort of odd or goofy was that McCain often talked about having experience that allowed him to understand the subtle nature of problems that our nation faced. However, he failed to demonstrate his insight. It made it look like he was just name calling.
