We aren't talking about "invalidating" a Constitutionally elected president. We are talking about removing a criminal, lying, mentally unstable, utterly unqualified buffoon who had the assistance of a hostile foreign power in getting elected. If he goes down, chances are good that Pence goes down with him. So, what we are actually talking about is Paul Ryan being president. I detest the man's policies, but at least he is sane and qualified for the office. There is NO excuse for voting for Trump. None.
