I am a photographer and was fascinated by the non-verbal signals that McCain was sending during the debate.  As Gladwell showed in his book Blink, you can't underestimate the importance of these signals.  In fact, as the campaign has gone along, McCain photographs of McCain have shown that he is presenting an increasingly angry and bitter face.  Look at the eye rolling, dismissive comments he made yesterday about Obama. 
An editor friend of mine who has seen many thousands of campaign pics over the last year confirms this.  Photo editors have an increasingly hard time finding pictures that don't freeze a scary, snarling face for all to see.  Contrast that with Obama, who is one of those people who almost never have a bad picture taken of them.  There's an occasionally goofy expression, but nothing that makes you think the man is possibly mentally unstable. 
Interestingly, under the toll of the Presidency, photographs now reveal Bush to be much angrier and less in control than at the beginning of his first term.  This probably reflects the enormous toll of being President.  
But McCain hasn't even been elected, so imagine what he will turn into if elected. 

McCain's push to limit the pay of executives that the new bailout helps to $400,000 raises several questions.  Does he only think that income for public businesses should be limited?  How about private companies?  Is it fair that Cindy's annual payout drawfs $400,000?

I've been waiting for a real examination of her business dealings.  What is their plan if McCain wins?  How much does she make in salary and benefits?

Isn't it time that we learned about the two kids Palin hasn't exploited for political gain?

My advice to Obama, for what it's worth.  Define McCain as a right wing maverick.  Something like this:

McCain certainly has proven he can change.  Since 2000 he's turned into a right wing maverick.  HisVP selection is the best example of this.  He's picked another right wing maverick for his running mate. 
By looking at her policies, we can see what the government of a right wing maverick would mean to the country.

A right wing maverick derides government earmarks, then rakes in as much as they can.  A right wing maverick believes abortion should never be allowed.  A right wing maverick believes that global warming isn't happening.  A right wing maverick believes creationism should replace the teaching of evolution.  A right wing maverick ... You get the idea.

The beauty of this is you don't even have to say Palin is inexperienced.  Use her existing record and keep repeating right wing maverick,  where you really mean right wing nut.
