I think Trump would do pretty well among liberal Democrats who don't like Gore, especially the ones who voted for Nader IOTL, with his support of universal healthcare and general reformist policies. In 2016, there were a lot of Bernie-to-Johnson voters even though their platforms were very different, so I can see a lot of Bradley-to-Trump voters here.
I wonder if Nader himself is actually doing better than OTL, because Trump's ITTL run has created more optimism for Third Parties.
