that sounds not totally crazy until you realize that you've just said that the president can kill all Congress members who think that killing Congress members is an impeachable offense
EDIT: to clarify: Any president up until now, and from now going forward, has the power to command his generals to murder every senator, justice, and governor. Of course, American soldiers take an oath to the constitution, so hopefully this wouldn't happen, but he could. Moreover, anyone can 'just' murder all living politicians and declare themselves king. This is hardly a theoretical scenario to concern oneself over.
