McCain has taken Obama on with his Hamas support/friends and Ayers.
"The Obama campaign also pointed out that the attack seemed to contradict comments made on MSNBC last month by McCain campaign senior adviser, Charlie Black, who said, "What Senator McCain has said repeatedly is that these candidates cannot be held accountable for all the views of people who endorse them or people who befriend them. ... He believes that people who endorse you, people who befriend you, are entitled to their own views, but you are not held personally accountable. That when somebody endorses you or befriends you, they're embracing your views, the candidates' views, not the other way around."
