The 2020 elections! Simply put, Trump may just let the Muller probe play out and then, at the end of the democrat primaries the first round of accusations (with some indictments) against key dems on the ticket roll out. Now this may very well turn the tide but after that and before the general election a second round of accusations, with some indictments, should roll out and effectively destroy all of the power players on the left. Trump will turn the page.
That is my theory!
Now we need to be fair and any repugnant caught up in this need to go as well but trump should take them out on the first round. We need to play the freaking game better than the left.
