It seems clear to me that the tRump is recognizing that he will very likely lose a free and fair election. He has been very actively claiming that there is going to be terrible fraud by the Dems.
It seems clear to me from what the tRump himself has said, that he hopes that the election will be contested and wind up before the SCOTUS to be decided. (And it is clear to me that he believes that this will insure his winning, since he plans to have another of his personal picks in the Court by then, with a conservative supermajority.)
With his corrupt sidekick being Attorney General, and the DOJ as a personal campaign support system, I would think that the manipulations to get the election thrown to the SCOTUS would not be particularly difficult to accomplish.
(Unless the VOTE is so heavily in favor of Biden, that such manipulation becomes impossible.)
