Contrast in Life Experiences

It's too bad USA Today put it at the very end of the article, but it's a good thing they pointed these facts out:

McCain, who has portrayed Obama as an elitist, is the son and grandson of admirals. The Associated Press estimates his wife, a beer heiress, is worth $100 million. Obama was raised by a single mother who relied at times on food stamps, and went to top schools on scholarships and loans. His income has increased from book sales since he spoke at the 2004 Democratic convention.

Seems like the "he's rich too" charge is just going to cause the media to get into Obama's life history and contrast it with McCain's life of privilege.

How long will it be until McCain plays the POW card to fend off the criticism of his elite out of touch-ness?
