If the GOP screws him over AFTER he signs I’m finished with the GOP.
Cant he later say something like this...I signed a pledge in good faith, but whatever.....
He could also say if Bush won...yes I said I would support the nominee, but the things he has said recently are more than I can take, hence I have to go back on my pledge for the good of the children...something like that
If they go on the war path against him,and he decides to quit the party after tearing that paper, I will also QUIT the GOP.
