Gary Johnson said he heard the boos on the stage and thought other candidates heard it, too. http://abcnews.go.com/blogs/politics/2011/09/arigop-candidates-react-to-booed-gay-soldier/ And, as I said, whether or not they heard the boos, I am pretty sure they heard the nonsense that Santorum spouted and the cheears for Santorum's nonsense.
Heh, funny that the least extreme nutjob on stage is the only one who heard it. Not that anybody on stage would've had the balls to call out the audience for their behavior. Every one of them were going to resort to the dog whistle BS that Santorum used.
its funny to see some republicans always claim to be independent. and no, i'm not talking about basso but the guy who always post an embarrassing democrat pic when someone posts a republican one
