all of the crazies were not invited to speak
Missing from the convention stage were ...
Sarah Palin
Michele Bachmann
Donald Trump
Herman Cain
Rush Limbaugh
Glenn Beck
and a bunch of the other crazy republicans like Orly Taitz, Victoria Jackson, Hank Jr., Ted Nugent, etc.
If they hadn't kept all of the nutty folks hidden away from the convention then there would have been tons of things to talk about other than only Clint Eastwood
