When President Obama and Gov. Mitt Romney meet for their third presidential debate on Monday, there will be some rules for the candidates — and the audience.
In the first debate, Jim Lehrer of PBS demanded "Absolute silence!" Although Lehrer caught some flack for letting the candidates freewheel in that debate, he meant business when it came to keeping the audience quiet.
"If you hear something that's really terrific, sit on it!" he told the audience. "If you hear something you don't like, sit on it!"
But that's not the only debate rule — not by far.
