I think J. D. Vance is a terrible person too.
But it takes a special combination of dumb luck, shitty personality and a reality TV show to convince all the morons in a country to worship someone. And so even if Vance does manage to become president he won't stay in power long.
In any case, it's time to use the 25h Amendment to remove Trump:
Section 4:
Whenever the Vice President and a majority of either the principal officers of the executive departments or of such other body as Congress may by law provide, transmit to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office, the Vice President shall immediately assume the powers and duties of the office as Acting President.
