I can certainly see your points. It of course remains to be seen what happens, if anything from SCOTUS. I do continue to just hope that our Constitution is upheld.
As for impeachment of a President, why would impeachment be necessary if the person was not a legal President to begin with? Do we impeach a usurper?
You asked — “As for impeachment of a President, why would impeachment be necessary if the person was not a legal President to begin with? Do we impeach a usurper?”
Well, very simply because an accusation is not proven until it’s been adjudicated in a court of law. In the President’s case, there has not been a court of law that has made that judgement. So, when he gets sworn in he *is* President.
And after that time of taking office, there is only *one venue* for “adjudicating” any violation of the law (in order to remove a President) — which is by Impeachment from the House — and — Conviction by the Senate.
Until such a time as a court of law adjudicates the matter — or — the Senate convicts him — he is the President, regardless of any allegations.
