The purpose of the Electoral College in the election of the president is to ensure equal representation of states in the election process. It was created as a compromise between having the president elected by Congress or by a popular vote. Each state is allocated a certain number of electoral votes based on its population, with the total number of electoral votes equal to the total number of senators and representatives a state has in Congress. This system gives smaller states a voice in the election process and prevents large, heavily populated states from dominating the election.
