The GOP has no long term future unless it can reach out to minorities & mostly young people. More young people come in & the electorate will only be getting more diverse.
6 of the last 7 times Dems want the popular vote, this time with more than 3M votes. On the long term there is no future for the GOP at the presidential level.
Trump was lucky to run against Hillary. Dems will get a decent candidate & Trump will face a big loss!
I think if Trump stays unpopular then he will likely to lose re-election and also on top of that if dems nominate someone like Tulsi Gabbard or Kamala Harris.
