<human>:  How does the electoral college system work?
<bot>: The electoral college system is an indirect system used in the United States to elect the president and vice president. Under this system, each state is allocated a certain number of electors, and citizens of the state vote for presidential candidates. The candidate who receives the most votes in each state then receives all of that state's allotted electoral votes. In most states, whoever wins the popular vote in the state receives all of that state's electoral votes. The candidate with the majority (at least 270) of the electoral votes wins the Presidency.
