" Republicans are far more likely to walk in to a polling boot than democrats and democrats are far more likely to use mail-in ballots.
So what could very well happen on in election night, you’re sitting there moderating show, it appears that Trump is winning in Michigan and Wisconsin and Florida.
People say it, oh my goodness trump is ahead and then in ten a clock in a night Trump announces, “I won the election and by the way my attorney general has told me there is massive fraud with the mail in ballots, and we got a stop counting those ballots. Thank you America , I won, have a good night!”
And then the mail in-ballots keep coming in and Trumps lead disappears and Biden becomes the leader. And then you have a massive chaos and conspiracy theory and that is the nightmare I’m worried about. "
