I watched it, Trump turned "funny and charming" into the audience, stop their laughing and loudly booing him for taking the modest poking fun at each other to a last public verbal assault on Clinton. Trump was so dumb, that when the audience booed he thought it was for his "target" of his assault on Clinton.  The elite in the audience are already familiar with the former 8 years of Clinton being a US Senator from NY  ( which she won a second term by 63% ) and NY state is her home and I am sure they are planning to stay on good terms with Madam President and run as far as they can from Trump. Ask Trump why NY state is 40 % in the polls for a Hillary win. Must be hard for Trump to lose his home state by that much when I heard him on the news that he was going to flip NY state for him.
