[Non-Sequitur]

Nearly every day of the week courts declare actions null and void, and turn back the clock to the date of the nullification and undo what has been done.

If there is a Constitutional basis for it. There is plenty in the Constitution detailing how to handle a vacancy in the presidency, but nothing in the Constitution allowing a do-over on elections.

Right. There would not be any new election because the Constitution does not provide for that. It provides for the House of Representatives to pick a President.

If the Court declared Obama ineligible, there would be no vacancy in the presidency, because the VP elect (Biden) would become the Acting President.

There would be no "do-over election", because the XXth applies without requiring another election.

But none of that will happen, because the USSC will not allow the case to be heard.
