Are you really that naive? Let me help. Because Bill Ayers is a COMMUNIST TERROR BOMBER, who was AND IS proud of his bombs and felt the Weather Underground didn't go far enough.
Do you really think Obama would have been elected with "By Barack Obama and William Ayers" on the cover of "Dreams of My Father?"
I think you are as naive as I am or perhaps more. The American People knew all about Bill Ayers and did not care. He could be on the cover with Obama and it would not have bothered the American voters (at least 54 percent). Now why on Earth would Obama put Ayers on his cover if he was only the ghostwriter?
