You apparently haven't been following it closely. Trump acting like this is what got him behind in the polls. It's what made him the most unlikable and divisive candidate in history. More of that is not helping him. I have no idea why that is so hard for people to understand. Yes, acting like a substance-less, loud, boorish buffoon has gotten him this far, but it's not enough to win the race. At all. How is a debate where he is acting substance-less, loud, boorish and buffoonish going to turn anyone to his side who wasn't already there? This is the key thing people like you seem to miss. Yes, it literally isn't over until it's over. Congratulations on that stellar analysis. But Trump's chances of actually winning are astronomically low.
