But if all the votes aren't counted yet - like what happened with the Bush/Gore election - then the Supreme Court or whomever makes these decisions could legally extend the timeline (however it happened before). Trump remains President then until it's sorted out.
And it probably would get sorted out. But my point is that there is historical precedent for a gray area of when an election is over - I mean come on, the Supreme Court had to decide when the Bush / Gore election was over, and Gore could have contested that, if he had chosen to.
So it's obviously a possibility considering how messed-up our electoral process could be this year from a combination of covid-19, neglect, and deliberate neglect. And possibly foreign sabotage though I'd put that at the bottom of the list.
> The terms of the President and Vice President shall end at noon on the 20th day of January
It could not be plainer.
Supreme court can rule about the process of counting, when the joint session to verify the votes happens, when a given state has to appoint its electors etc, but can't possibly interpret this as anything other than the plain text it says.
