Body Language Bares Rivals' Key Differences

The presidential hopefuls are saying a lot more than just words, reports LiveScience. Body language experts analyzing John McCain and Barack Obama's movements have discovered major differences in the kind of leaders they are likely to be. McCain's firm stance and tendency to grip the podium send out a message of stability, while Obama's looser movements hint at change, they say.

Analysts believe both men show auspicious signs of introspective qualities that indicate they'd be effective leaders, but Obama's more relaxed movements may give him the edge. "John McCain is ill at ease a lot," one analyst said. "Obama is rarely ill at ease although he's put on the spot. McCain sometimes looks like he's looking for the door. He needs to work on that."
