I agree with you, Kelcarry, that the current occupant of the oval office is an egotistical ass, and the worse president that I can remember. That said, the LAST occupant of the oval office was, up until January 2009, the worst president in living memory.
I don't see Doc as being unnecessarily argumentative; in fact, he said "I'm not disagreeing, just wondering."
I think that it just goes to show that every one of the narcissistic egotists that achieve the office of POTUS (let's face it, you have to be fairly full of self to seek the office) deserves every last bit of distrust that we can show them. Even if my man Ron Paul were elected, he would have to prove everything he said. As they say, power corrupts, and absolute power corrupts absolutely.
