Section 4: Declaration by vice president and cabinet members of president's inability

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.

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.

So, in an absolute best-case scenario, we're asking for a schism between Vance and Trump wide enough such that Vance secures a majority of support among executive departments (a thing that is never going to happen) which only endures until Trump tweets "Nuh uh, I'm fine". At which point, the issue is deflected to Congress, a body that is fully in the tank for Donald Trump.

Y'all are choking to death on Copium if this is what you're all waiting for.

FFS, half the Democrats in Congress tacitly endorse Trump's Iran War. The only real objection they've made is that Trump didn't ask nicely for their blessing before the bombing began. Schumer, Jeffries, and the rest abhor the IRGC and are all in favor of bombing them into a fine powder. The bulk of the DC liberal establishment had no problem funding this war via the NDAA, which passed with a majority of Democrats in favor. They have no problem with killing civilians, as evidenced by their fixation on war costs over human casualties. They have no problem with the high price of energy, as evidenced by blue state governments' refusal to impose rationing or fast-track alternative energy infrastructure. The liberals are not going to save you.

The "moderate" Republicans in Trump's own cabinet certainly aren't going to save you. Mitt Romney is not coming to the rescue. John McCain is fuckin' dead, bitch. Lindsey Graham is currently in the Boy Tent absolutely flogging himself in ecstasy over this war. Howard Lutnick and Scott Bessent are making eight figure bets on polymarket with his insider info. Linda McMahon is in the cuck chair watching her husband sodomize an intern. Sean Duffy is off finding new train lines to cut because they're Woke. These are your rational moderates who are supposed to check Trump's war.

It's not happening.
