Who is bill Ayers and is he a friend of Obama?

It may be far fetched, but Obama could be just a part of Ayers plan. He could not get anywhere bombing america and spewing hate for america. So, like the mafia, he decides he can accomplish his goals, which is to have a socialist society like the communists, by going "legal". Instead of bombs he sets out to take over the government starting at the top. Obama's claims that "I hardly knew Ayers" are ridiculous. He wrote a blip for ayers book. Why would you do that for someone you hardly knew? Even though together they doled out milllions of dollars? This is where Obama shows himself to be a liar. Just like with his mentor and pastor of 20 years, he didnt know what his preacher was preaching about. How stupid do the dems think the voters are?
