Every person who preceded Trump handed over their prospective speeches. Those speeches were vetted, formatted, and uploaded to the teleprompters. And, all those revolting things were said over the course of HOURS before Trump took the stage. You know that media hound was tracking the live chatter of his event before he stepped out in that arena.
It seems to me that Trump isn't even trying to win the election. He's hardening divisions and deliberately shedding voters. He's just whipping up his core bse — his army of fanatics — to violently overturn the election.
