You know very well that Trump signing a pledge he will not run as an independent was a waste of ink and paper. If (When) he is not the GOP nominee, he will run as independent and will say he is great businessman and the pledge was bogus - and that he will treat any treaty or contract the same way when elected President.
Yes, the independent party would lose against the Democrats! Hillary AND America wins!!!
Reactionaries have shot themselves in the foot again - this time it might be a fatal shot to their party. AWWW.
