McCain Asked the FORBIDDEN -- Heidi Ho -- Q

John McCain was blindsided by a Heidi Montag question outside a rally in Pensacola, Fla.

McCain didn't have much to say -- but his bodyguards did, rushing the photog off-camera and threateningly asking why he'd ever ask a question like that . It's like someone asked him about bathrooms and airports! Why is Heidi such a scandal? Is it too hot for McCain to address? We're just sayin'.....
