An elector is a person who has the right to vote in an election. In many democratic systems, electors participate in choosing representatives, such as members of a legislative body or a head of state. Their votes help determine the outcome of elections and influence government policies. In the context of the United States, electors also refer to members of the Electoral College, which is responsible for formally electing the President and Vice President. Each state has a set number of electors based on its population, and these electors cast their votes following the results of the popular vote in their state.
