According to The Huffington Post, according to Newsweek, John McCain said, "I never considered myself a maverick."
I never thought of him as a Maverick, either. Maybe more of a James West, minus the low-rent-007 charm and coolness. Which leaves you with a short, bellicose jerk.
(So that would make Sarah Palin Artemus Gordon, minus the proto-MacGyver gadgetry and disguise kit. I guess. I refuse to take this premise any further. Ecch. I just involuntarily pictured Ross Martin in lipstick, high heels, and a designer dress purchased with RNC funds. Yucch. Hm, they do kind of have the same nose. OK, OK, that's it. I'm done.)
