The only way Trump is going to start his 2nd term is to somehow overturn the certified electors, which means the Trump/PENCE electors get chosen instead.

There is no way to insert anyone else because the states have sent electors for TRUMP/PENCE or BIDEN/HARRIS, nothing else.

The CONSTITUTION only has one way to replace a Vice President, and that is if both House and Senate agrees.

https://en.wikipedia.org/wiki/Twenty-fifth_Amendment_to_the_United_States_Constitution

Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress.

Let's not be delusional fools and LARP about a new administration suddenly having Patriot General Flynn as VP. NOT GOING TO HAPPEN!
