If McCain has won there is good possibility he would have never served out his presidency. He would have been the oldest president in American history, one who has all sorts of health issues. So this posting is not wishful thinking. If McCain had ran like a conservative, he would have won. If the GOP keeps nominating worthless RINOs they will never retake the White House.
He wouldn't know how.
Incorrect. Reagan was 73 when reelected and just shy of 74 when sworn in for the second time. McCain would have been 72 if elected and sworn in.
