McQueeg might be the worst person to be commander in chief. While we know he's willing to use the military, he seems just too ready to use the military and to use it indiscriminately. And, if we are going to have a long protracted war, we need a Commander-in-Chief who knows how to use limited resources carefully and not to squander them on sideshows. From all his rhetoric, I doubt McCain knows how to do this. And, since it's become obvious that he wants to continue Bush's policies, (which albeit appeared sound before he decided further adventures in the Balkans were in the US best interest), nothing would dilute American foreign policy as effectively as pointless misadventures in parts of the globe where we have no strategic interest.
John McCain opposed protecting our borders and voted against barring gang members and terrorists from entering this country. He also giggles and talks to himself and on national TV when he knew the cameras were on him. He looks like he is about to have a breakdown.
