honestly, nothing is more entertaining (and more deserving) than Trump/Trump supporters destroying the GOP.
Trump should start his own third party.
If it were possible for him to do it at this precise point in time, it might destroy the Republican party. I'm not a Republican, but in my opinion, that would be very bad for our country. If Trump were to attempt to start his own third party, it would just further prove that the man is all about himself and he doesn't give a shit about anyone else.
