This is not a threat, it’s a fact. The GOP is a hollow, empty shell without Trump. It will be tossed around and consumed like a kitten at a gator farm without him.
The GOP without Trump is Fox News without Conservatives. Within weeks Fox went from being long running king of the hill to losing a majority of their viewers. Within 3 election cycles (the minimum to run everyone thru again), I would be surprised if we had double digit R representatives in Fed Gov. (and they would all be Senators that make it thru 2022)
