ST. LOUIS (KMOX) - When President Obama and Mitt Romney hold their third and final debate in Florida tonight, you should pay attention to more than just what they say.

You should notice how they stand, motion, and even their facial expressions. That’s according to body language expert Patti Wood.

Wood, the author of “Snap: Making the Most of First Impressions,” says one thing we will be looking to see is if they’re still sparring.

“Can both of them talk about what they’re going to do and move forward on the stage, smile, as they talk about plans for the future instead of using angry body language to make their points?”

Wood says their tone of voice also gives cues to which candidate is the “alpha dog” and is going to be the better leader.
