I watched the entire speech on TV. Trump never did pronounce Oregon correctly and it seemed no one had the stones to correct him. He doubled all estimates of the attendance at previous rallies, even adding numbers to his earlier statements about the attendees. He also seemed unaware of voting by mail, saying to make sure and vote, "not this Tuesday, but next".
I like some of the statements by Trump. A few months ago he railed against the drug companies. 
The Framers knew that voters could get swept away by a demagogue and elect a tyrant. Fortunately, they included checks and balances to keep another king from controlling the country. So I am not too worried about Trump being elected.
But if he is not elected, what are his supporters going to do? As Trump might say, "time to go home to Mommy"?
