The president cannot install a full blown monarchy under the powers vested by him in the constitution. Neither can congress.

The issue though is in the case where Trump is installed in a second term after members of congress are kidnapped, extorted, or even executed, then the question of what is and is not constitutional becomes moot. The application of force in the political process has a tendency to degrade all guard rails, leaving behind nothing but “largest army diplomacy”, or mob in this case.

To whit: “stop quoting laws to those of us with swords”.
