Thereafter, when the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that no inability exists, he shall resume the powers and duties of his office unless the Vice President and a majority of either the principal officers of the executive department or of such other body as Congress may by law provide, transmit within four days 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. Thereupon Congress shall decide the issue, assembling within forty-eight hours for that purpose if not in session. If the Congress, within twenty-one days after receipt of the latter written declaration, or, if Congress is not in session, within twenty-one days after Congress is required to assemble, determines by two-thirds vote of both Houses that the President is unable to discharge the powers and duties of his office, the Vice President shall continue to discharge the same as Acting President; otherwise, the President shall resume the powers and duties of his office.
Note that "two-thirds of both Houses" criterion. I read it that a determined resistance by the Republicans could return the Drooler to office. Part of me knows how bad that could be for the country. Part of me thinks it'd be funny as hell.
It would be funnier than hell if they denied the 2.3rds vote. Would be like a Monty Python sketch only live.
Or Democrats happier with a well controlled puppet rather than Harris as president.
