Sad. I am sure that at one time Senator McCain was an exceptional representative of his state, with an ability to maneuver in the whacky halls of Congress. As people become more informed and he falls into the morass of being a career politician, he has lost his way, standing for apparently no principles beyond an opinion on a current crisis. And Senator Graham not believing the drone question was valid? If it was such a ludicrous question, why weren't the Attorney General or the President able to provide a simple rapid answer? They had to be beaten about the head and shoulders with a filibuster...it's possible principles and integrity do matter, even if many career politicians have neither.
