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). Iowa has 4 House seats + 2 senators = 6 electoral votes.
A candidate needs 270 out of 538 electoral votes to win the presidency. Iowa’s 6 electoral votes represent 1.1% 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. Iowa uses the winner-take-all system.
