Is there any mechanism, other than impeachment (for a crime) or resignation by which a US president can be removed from power? Other countries have a "No Confidence" vote that can remove a leader or leading party from power forcing a new election, and some states have a recall mechanism for governor.
Is there anyway we can have a new election before 2008?
"Is there a "No Confidence" mechanism for US presidents?"
As a practical matter, no. There are two constitutional clauses for removing the president - Article II, Section 4, which reads:
"The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors."
The only attempt to use this mechanism that was pursued to its conclusion was with President Andrew Johnson, who was narrowly acquitted.
The other clause that offers any type of mechanism for removing the President is the 25th Amendment, which reads as follows:
Section 1.
In case of the removal of the President from office or of his death or resignation, the Vice President shall become President.
Section 2.
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.
Section 3.
Whenever the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that he is unable to discharge the powers and duties of his office, and until he transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the Vice President as Acting President.
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.
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.
Given that the Vice President and the cabinet are typically selected by the President, and with the exception of the VP serve at the pleasure of the President, this mechanism would require the individuals holding those offices to believe 1) that their oath of office to their country exceeded their loyalty to the President, and 2) that their commitment to the rule of law in this country exceeded their loyalty to the president.
