I think you are referring to the electors who make up the electoral college that officially elects the President and Vice President.
They can elect the president if none of the candidates have a majority vote. They can also impeach people.
If there is not majority in the Electoral College, the vote goes to the House of Representatives. The president is then elected by a majority of states representatives.
The US Congress has this power. The House of Representatives starts the impeachment proceedings but the Senate has the final vote.
No, the US Constitution requires that treaties be approved by 2/3 vote of the Senate.
The impeachment process begins with a bill in the House of Representatives and concludes with a trial in the Senate.
In the House of Representatives if a vote ends in a tie, the matter fails. However, in the Senate if a tie results, the Vice President can cast the deciding vote.
If no candidate gets a majority, the House of Representatives chooses using a special procedure in which each state gets one vote.
House of Representatives makes the decision.
yes they can be changed by a vote among the house of representatives and the president.
If no one receives a majority vote, the desicion goes to the House of Representatives.
the house of representatives and the senate
Under the United States Constitution, the House of Representatives must vote to impeach the president. It requires a simple majority vote for the measure to be passed and sent to the Senate for trial.
