Some interesting articles from the Huffington Post about McCain's and Palin's body language and what it tells us about them.

Body Politics: What McCain's Smirks, Tics And Jaw-Clenches Really Mean

Any good therapist learns to read the language of the body, but you don't need an advanced degree to understand John McCain's. His patterns are about as subtle as the flashing lights on a sign that says "Danger Ahead."

McCain's Body Language: He's a Hater

Many people, including the punditocracy, commented on McCain's body language during the first debate.

I believe that conclusion is wrong. Instead, I believe it shows that McCain literally hates Obama, and was not able to control his reactions. For example, Hillary Clinton also had disdain for Obama, but she did not hate him. She looked at him, and her body language engaged him during the debates.

Moreover, McCain seemed afraid. When Obama looked McCain in the eye, McCain looked away. McCain's usual reaction to fear--lashing out, and adopting the body language of an attacker that often makes the other person step back so as to avoid a conflagration--is unavailable to him in a debate setting, and so all he can do is retreat in fear.

Body Politics: Sarah Palin's Body Language And Why It Should Worry You

Sarah Palin has mastered one fundamental requirement of a Republican president: she can smile and look you directly in the eye while telling an outrageous lie. At least when John McCain lies, his body screams his discomfort by putting on an eye-catching display of twitches, phony smiles and robot moves. McCain's body language is so strange that it's easily observable; he appears to be operated by a puppeteer who is a couple of triple-espressos over the line. That's a good thing, though. We'd much rather have a presidential candidate who reads like a comic book when he's lying than one who conceals those whoppers under a grin and a wink. Sarah Palin belts out her deceptions and distractions with a radiant confidence we usually only see in sociopaths and infomercial pitch-persons. The last public figure we saw who could grin and lie with that kind of sunny confidence was O. J. Simpson.
