McCain is selling the farm without asking for the price. This good guy bullshit on his part is wearing very thin.
Reagan would walk into a room full of people who hate him (liberals, Chrissy Matthews-Olberman sorts) and smile, not because he thought they liked him, but because HE DIDN'T CARE that they didn't like him.
McCain would walk into that same room and smile because he BELIEVED they really liked him.
If Reagan were to give that same response that McCain did about Obama, he'd say off-handedly "My opponent is a good man" but you'd know he didn't mean it, and he'd smile while people laughed--THEN he'd go in for the kill.
People talk about Reagan's seemingly benign, grandfatherly personality, but they forget he was stubborn when it came to the really important things (Russia, taxes).
McCain only does the first part (the nice guy stuff), and somehow thinks that makes him Reaganesque.
