What are your thoughts on a political figure threatening legal action against opponents if they win an election?

Back when I was in the Army in W. Germany (PFC- SP/4-Sp/5) I would of been shot for what Trump allowed an incited.

This is how Rome turned to empire. Normalization of violence or threats of violence in the political process.

My thought on a political figure threatening legal action against an opponent they won over seems childish and unprofessional on how you close down on a dispute after you won.

Threatening legal action against political opponents for winning an election is an undemocratic and authoritarian tactic that undermines the integrity of the electoral process and the peaceful transfer of power.
