If that is to be so, then Pence is going to have to adopt much, much more Trumpesque than he naturally possesses now. The ONLY reason the Tool was able to win the needed electoral votes he did is simply because enough folks recognized him as a HOPEFUL tool of change to politics as usual...
Pence, otoh, is conservative - solidly bordering on rINO - politics as usual at its staidest.
Unless you want to see a flaming progressive come out of nowhere to win in 2020 like Trump did in 2016, you best hope the Tool is around for reelection.
