The Electoral College is made up of 538 electors who cast votes

Court House - The Electoral College is made up of 538 electors who cast votes to decide the president and vice president of the United States. When voters go to the polls, they will be choosing which candidate receives their state's electors. The candidate who receives a majority of electors votes (270) wins the presidency. The number 538 is the sum of the nation's 435 representatives, 100 senators, and three electors given to the District of Columbia. The electoral vote ensures the rights of smaller states and stands as an important piece of American Federalist democracy.
