Presidential candidates in the United States win elections by winning the most electoral votes.
The Electoral College system apportions a certain number of votes to each state. When voters in a state vote for a party’s candidate, they’re actually casting a vote for that party’s slate of electors, or people chosen to cast electoral votes.
