Smart and determined, maybe. Coniving,liar, mostly. Sincere, I doubt he knows the meaning. As for giving his life for his country- the guy isn't dead. Old yes, but not dead yet. John McCain hasn't given anything without getting something in return, remember 150+ lobbyists- 10 Personal Residences in the US (all worth over $1 million a piece). He is not a veteran of combat, his lack of skill from lack of training because he was always partying landed him in prison through out the Vietnam War and so he has no experience there. He's been bought and sold so much his expiration date is open ended.
