And one scenario in particular has Democrats nervous: the lawsuit-happy Trump contests the election results in court.

“It’s been a worry in the back of my mind for the last couple years now,” said Rep. Brendan Boyle, a Pennsylvania Democrat. California Rep. Ted Lieu, a frequent Trump critic and early impeachment inquiry supporter, acknowledged the same concern but said he trusted law enforcement “would do the right thing” and “install the winner” of the election. Even House Speaker Nancy Pelosi has told her party to prepare for the possibility that Trump contests the 2020 results.

Constitutional experts and top Republican lawmakers dismiss the fears as nonsense, noting there are too many forces working against a sitting president simply clinging to power — including history, law and political pressure.
