It is looking grim for tRump. There is no "Weiner laptop" and "James Comey" moment to work for tRump. The Guiliani "Hunter laptop" was a galactic bust. In fact, it may have backfired.
Now, it could very well be possible that after losing, tRump resigns. This would allow Pence to assume the office of POTUS and pardon tRump. With the loss, the Pence political career is over anyway. As such, he has nothing to lose.
It is very likely that tRump has significant worries about going to jail. If the Senate flips, the chances are very high that tRump will face legal issues. In lieu of this, a tRump pardon would certainly provide tRump a safety net of sorts.
