Each state’s Electoral College votes mirror its representation in Congress

The Electoral College, explained

The US presidential election hinges on the Electoral College, not the popular vote—a system created in 1787 as a compromise. Candidates must win 270 of 538 electoral votes, allocated by each state’s congressional representation.

How the Electoral College actually works

In settling on the rules for how the US elects presidents, the Founding Fathers coalesced around a system built on two inputs: Votes from individual voters, and the accumulation of votes from specially chosen Electors. The latter comprise the US Electoral College, and this Washington Post article explains why it exists, how it works, and how its 538 electors collectively decide presidential elections.

What is the Electoral College?

US presidential elections are not “majority rules” contests. A complex mechanism underpins them, guided by the Electoral College system established by the Constitution. This US government website offers an overview of that system, which apportions “electors” for each state and requires winning presidential candidates to secure at least 270 Electoral votes on election night.

Why the Electoral College exists and how it works

The framers created the Electoral College as a compromise between electing the president by popular vote or by Congress. It was meant to balance power between large and small states and to allow elites to intervene if voters chose an unfit candidate.

Electors are chosen by states and political parties

The Electoral College was shaped in part to balance North–South power

Supporters argue that the Electoral College strengthens federalism and election stability

Defenders of the Electoral College argue it preserves federalism, forces candidates to build broad national coalitions, magnifies victory margins to reduce recount disputes, and limits incentives for voter fraud by containing the impact of contested ballots within individual states.

270 electoral votes decide the presidency

A presidential candidate is declared the winner once they reach 270 of the Electoral College’s 538 votes. This interactive map from 270 to win shows how winning individual states shifts the path to victory on election night.
