And besides...

POTUS is going to try to recreate conditions and actions that he took in 2016 ahead of his re-election. In 2016 when he said things like this, there were a number of members of his own party who objected. It is now his party, and he knows he will face little to no pushback. https://t.co/fSOHD7zdx9

...as the saying goes, when someone tells you who they are the first time, believe them. I think most people do, by now:

Our new NBC/WSJ poll results are our first hypothetical general-election matchups for the 2020 race:

Biden 51%, Trump 42%
Sanders 50%, Trump 43%
Warren 48%, Trump 43%
Harris 45%, Trump 44%

(July 7-9, MOE: +/- 3.5%)

Of those four, Harris is the least well known, but she ties with Trump.  It's early, but the incumbent is not showing well.

And trying to recreate the election you won the first time is not exactly a recipe for success....
