I recall the "That one" comment which McCain made during a debate, in regard to Obama. I don't know whether McCain believes Obama is not worthy of professional courtesy, as a result of Obamas ties with Rev. Wright and Bill Ayers, thereby beieving he is right to resort to treat Obama with contempt, or McCain is as bull headed as Dubya.

If Obama does share the beliefs of Ayers and Wright, then McCain would be justified to express such contempt, but if not, then it would appear McCain will hold contempt for anyone who gets in his way and doesn't agree with him.

Either way, both candidates could be a liability.
