Winning and losing debate body language

Tuesday’s town hall style presidential debate will require the candidates to flex different debating muscles. Body language expert Janine Driver walks Anderson through some do’s and don’ts.

Mitt Romney has been known to point his finger to express himself, which Driver says can be seen as "aggressive." The open palm is a more appealing move.

The "thumb of power" is another hand gesture often seen at debates or when candidates are speaking to a large audience. "It's a combination of chopping and pointing. It's much better and softer," says Driver.

Another tell is when one hand is wrapped around the wrist of the other hand. Driver explains this behavior as "the higher the hold, the more anxiety is told."

Specifically in the town hall setting, a challenge for Mitt Romney and Pres. Obama is how to react to the person asking the question, while engaging the larger audience. Driver believes it's a mistake to listen to the question and immediately turn to the audience to work the crowd.
