It won't even have to be a movement. If the elitist backstabbers steal the nomination, we don't have two parties anymore. It would be better to let the Republican Party die, and let an opposition movement emerge from the Democratic Party. The only other option would be for someone denied the nomination to run as the candidate with an established 50-state third party, choosing an impressive running mate. Campaign donations won't be an issue; the difficulty would be in keeping up with how much money comes in.
I hope it doesn't come to either of these scenerios, that saner folks prevail, and the Republican leadership cleans up its act before the convention. That would have to include a delegate process that denies seating anyone whose claims to representing the voters is questionable.
The people who are claiming to be the saner folks are leading the #NeverTrump, #StopTrump, #DumpTrump efforts.
They are absolutely determined that the laws will not be enforced and illegal aliens will be allowed to stay.
Our country is being stolen from us.
