Extremely predictive quote in The Atlantic, November 2020 edition:
"The worst case is that [Trump] uses his power to prevent a decisive outcome against him. If Trump sheds all restraint, and if his Republican allies play the parts he assigns them, he could obstruct the emergence of a legally unambiguous victory for Biden in the Electoral College and then in Congress. He could prevent the formation of consensus about whether there is any outcome at all. He could seize on that uncertainty to hold on to power."

This unsubstantiated "voter fraud" narrative is precisely the uncertainty Trump's goonies are trying to manufacture. I think it fails, particularly because key state and local officials and judges don't seem to be playing ball, but the majority of national-level elected Republicans' silence right now is deafening.
