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). Idaho has 2 House seats + 2 senators = 4 electoral votes.
A candidate needs 270 out of 538 electoral votes to win the presidency. Idaho’s 4 electoral votes represent 0.7% 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. Idaho uses the winner-take-all system.
