Section 4 of the 25th Amendment says:
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, transmits 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.
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.
Who has been leaking the recent stories about Bush drinking, and about his profane tantrums at Camp David??
Whose office has the most history of targetted leaks and orchestrated lies??
Most of this Cabinet are no-names, and I have no basis to judge where their loyalties likely lie, but I'm assuming Rumsfeld would certainly side with Cheney, and Rice would go along if she was promised the Nomination in 2008 (she doesn't think they would lie to her).
Would a majority of the Cabinet back Cheney??
Would it matter if Cheney formally took over??
Is this where the reported rift between the two "camps" is headed??
