Who elects the US president?
When Americans cast their ballots for the US president, they are actually voting for a representative of that candidate’s party known as an elector. There are 538 electors who then vote for the president on behalf of the people in their state.
Each state is assigned a certain number of these electoral votes, based on the number of congressional districts they have, plus two additional votes representing the state’s Senate seats. Washington DC is also assigned three electoral votes, despite having no voting representation in Congress. A majority of 270 of these votes is needed
