Meanwhile, back to the topic of the OP.

I don't ever diagnosis some one I have not done a face-to-face evaluation of, but it does appear that McCain was confused and possibly exhibiting some cognitive impairment. I am not a McCain fan, but he is one of the few Senators still in office who does occasionally stand up for the country instead of his party - not nearly often enough, but more so than any of the younger Senators, whether from the GOP or the Democrats.

Unfortunately, in this instance, he not only appeared confused, but was also attempting to play politics rather than engaging in statesmanship.

Our federal government lacks any statesmen/women at all at present.
