McCain is a miserable, nasty, hotheaded SOB.
I recall him back in the 1990's, during kerry the Traitor's Senate Select Committee on POW/MIA Affairs.
We met him and tried to talk to him about the committee and present evidence and our positions on the possibility of POW's still being alive in SE Asia. He blew up and essentially called us liars, unpatriotic and rumor mongers among other things.
Then, the Traitor, kerry, said later that there might be "a couple of hundred" men left there. So what? "What do you want us to do, go back to war for a few hundred men?"
Well, no, just don't normalize relations until they're accounted for.
McCain, a former POW signed off on the committee findings, which totally disregarded numerous eyewitness sightings of living POW's. American troops we had left behind.
Only Senator Grassley and former Sen Bob Smith (NH) refused to go along with the findings. To this day, unfortunately, neither can talk about the committee.
