Posted: Updated:

PHOENIX -- With three week to go until Election Day, presidential contenders Barack Obama and Mitt Romney met face to face for the second of three debates.

This one was a town-hall style event with questions coming from undecided voters. The Associated Press described it as "crackling with energy and emotion."

That energy and emotion didn't just from from the repeated disagreements between the two. Just as important as what Obama and Romney said out loud were the messages their body language conveyed.

Renate Mousseux is an expert on body language. She went through some video clips and photos with  Javier Soto Wednesday morning to discuss the messages Obama and Romney delivered in addition the words they exchanged.
