<human>:  How does the electoral college work?
<bot>: The Electoral College is a system in which the members of the United States Congress, known as Electors, cast ballots to elect the President and Vice President of the United States. These Electors are selected on a state-by-state basis, with each state’s number of Electors equal to the total of their Congressional delegation - their number of Senators plus the number of Representatives they have in the House. On Election Day, voters in each state cast their ballots for the slate of Electors pledged to the candidate of their choice.When all the votes have been counted, each state's Electors meet to formally vote for President and Vice President. Each state’s Electoral College votes are then certified by its Governor and transmitted to the U.S. Congress, where the votes are formally counted. The candidate receiving the majority of Electoral College votes (at least 270) is declared the winner and the newly elected President and Vice President of the United States.
