Those who heard the "debate" blinked when McCain said, "Going back to the justices" -- before he was asked any questions about the US Supreme Court justices.
Whispered rumors started to come out that he had been coached ahead of time. It has now been confirmed that McCain was not actually in the building, but was in his motorcade arriving. On a cell phone. With his staff. Who all have Blackberries, and were likely wired into the debate live.
So pretty much, the entire debate with secret questions was a total sham.
