When Trump loses the coming election, a peaceful transfer of power should go from Biden to Harris, but Trump has worked to dismantle norms such that we must now expect that he will contest the results, tell his supporters he won, and worry about those angry supporters being goaded into attacks on poll workers, judges, Congress, and federal buildings.

Vance is already feigning ignorance of how he and Trump create violence.
Excerpt of Vance/Bash kerfuffle (page is not the full conversation):

... You accused me of causing a bomb threat. Doesn't that mean I should shut up about the residents of Springfield? Don’t you realize you're engaged in basic propaganda to silence the concerns of American citizens?

DANA BASH, CNN: I was quoting the actual mayor of Springfield, Ohio, who, after the bomb threats, was begging federal officials to stop putting negative attention on his city. I'm not talking about the policies....

They are making a peaceful transfer more difficult by telling lies, spurring on their most violent supporters, and then denying all culpability. Sadly, doing so may spread from their fanatics to a larger population as evinced by yet-another-gunman-incident.
