A more thorough explanation:

A presidential elector is a person who is chosen to cast a vote for the President of the United States. They are part of the Electoral College, which is made up of electors from each state. The number of electors each state has is based on its population.

For example, California has 55 electors because it is the most populous state, while Wyoming has only 3 electors because it has a smaller population.

During a presidential election, voters in each state cast their ballots for the candidate they want to win. The candidate who wins the most votes in a state gets all of that state's electors. The electors then cast their votes for the President based on the results of the election in their state.

For example, if a candidate wins the popular vote in California, all 55 of California's electors will cast their votes for that candidate.

Presidential electors play an important role in the election process, as they ultimately determine who will become the President of the United States.
