George Washinton and Thomas Jefferson were red-heads. Actually, I like this designation. McCain went with the white and balding look, and Biden went with the massive hair transplant plugs. remember how bald he was 20 years ago. Similarly, Obama's graying looks too much/too fast to be natural. I suspect there was a dye judge to make him appear older and more experienced.

You may be on to something, MaryCas.
