Maverick!! I liked that TV show -- James Garner -- good times...
McCain never led anyone or anything. The only notable thing he ever did was get shot down. I'm not belittling how horrible being a POW must have been, but that experience does not qualify him for anything other than being able to talk about what it takes to be a POW.
Military leaders don't make good presidents. Ike is a good example. They are used to giving an order and having it obeyed rather than having things debated, filibustered, altered in committee, etc.
McCain is not a good civilian or military leader. He is not a leader. Voting with Bush 90% of the time, he has shown himself to be a good follower.
