Who are electors?? (what they are)

The president and vice president of the United States are elected by the Electoral College, which consists of 538 electors from the fifty states and Washington, D.C. Electors are selected state-by-state, as determined by the laws of each state.

What do the electors actually do?

When citizens cast their ballots for president in the popular vote, they elect a slate of electors. Electors then cast the votes that decide who becomes president of the United States. Usually, electoral votes align with the popular vote in an election.
