John McCain is losing it.
I have seen it before (in person), when pushed or seen to be losing his momentum - he goes off the deep end.
John McCain is a friggen nut case - it's really too bad.
John McCain is a scary thought as a potential president. While he generally manages to look halfway sane, I have seen occasions where his eyes exposed an insanity that is eerie to behold. The man did a great service and suffered greatly as a POW, but he does not belong in government, much less as President..
