Hillary Clinton’s decision to stand by her husband and attack former White House intern Monica Lewinsky when news of a sexual relationship between the two broke in 1998 prove that the former secretary of state is “too stupid to be president,” Rudy Giuliani said Monday night.

Yeah, how did Rudy do running for the position?
