Trump will reduce the negatives as he did state by state. People once they see Trump speak will vote for him.
Hillary will be zero motivating factor. No energy for the Dem voters - though they will put out ‘street money’ to try to get them to show up.
Trump will destroy her in the debates (if she’s not incited first) and win the general easily.
I think it's something beyond that. Drawing on my own experience ( ahem ) I think people have decided that there's a massive campaign underfoot to dissuade them from voting for Trump ( duh! ) and are hence at this point steeled and determined to vote for him all the way - NO MATTER WHAT!
