How Third Parties Impact U.S. Presidential Elections
Third-party presidential candidates rarely win the White House, but their influence can extend well beyond their share of the popular vote. They can affect which major-party candidate wins a closely contested state, shape campaign debates, bring overlooked issues into public discussion, and influence future party platforms. Understanding how third parties affect U.S. presidential elections requires looking at the Electoral College, state election rules, voter behavior, and the lasting effects of campaigns that fall short of victory.
