How do you fight terrorism when you are friends with one?

Yes, its my question about Obama's character. He has had a 20 year relationship with William Ayers an unrepentant terrorist, that he is not being up front about! Why is he lieing to Americans? More importantly is America so desperate for a black president that they dont care about the facts? His ociations need some explaining. I like what he says but cannot vote for a man that hangs out with a man that bombed our pentagon...killed innocent americans. This is outrage!
