Bill Ayers' 1974 manifesto, "Prairie Fire", featured a dedication to "all political prisoners in the U.S." - including Sirhan Sirhan, the assassin of Robert F. Kennedy.
Barack Obama endorsed one of Ayers' books, calling it "Searing and Timely".
So here's the deal:
Ted and Caroline Kennedy gave their Presidential endorsement to Barack Obama, who endorsed a book penned by Bill Ayers, whose 1974 manifesto was dedicated to Sirhan Sirhan, the assassin who murdered Robert Kennedy - which means Ted and Caroline Kennedy endorsed their brother's killer......... and so did Barack Obama.
