Electoral College Basics
The United States uses an Electoral College system to elect the president. Each state receives electoral votes equal to its total congressional representation: number of House seats + 2 (senators). Pennsylvania has 17 House seats + 2 senators = 19 electoral votes.
A candidate needs 270 out of 538 electoral votes to win the presidency. Pennsylvania’s 19 electoral votes represent 3.5% of the total needed.
Most states use a winner-take-all system — the popular vote winner receives all electoral votes. The exception is Maine and Nebraska, which allocate electoral votes by congressional district. Pennsylvania uses the winner-take-all system.
