It does not get more serious than this. The Trump campaign is preparing to destroy democracy and execute a coup d’etat that will be the end of Constitutional government in our nation. The mechanism will be phony claims of massive voting fraud as an excuse for Trump friendly state legislatures to ignore the votes of the people and send their own Trump electors to the Electoral College. Attempting to hamstring the Post Office is part of the preparation for this coup.
These now well-documented preparations for this coup are all the evidence that anyone should need to vote for Biden. A landslide victory for him is the only way to prevent this disaster. With these developments it is IMPOSSIBLE to claim to support the Constitution if you continue to support Trump.
