Electoral Decoder

Welcome to the Electoral Decoder!

Every four years during federal elections, United States citizens go to the polls to vote for the candidate they want to be the next president.

But that’s just one part of the election. The U.S. Constitution requires a process called the Electoral College, which determines the outcome of the election.

The Electoral College process assigns votes to each state based on population—so, the more people who live in a state, the more electoral votes that state will have.

This tool uses a cartogram to help you visualize how each state’s electoral votes affect the outcome of an election. The more electoral votes that a certain state has, the larger it appears on the cartogram.

To learn more about cartograms and the Electoral College, click View Instructions. Or, to explore electoral votes for all past presidential elections and to predict the outcome of the current election, click Explore Elections!
