What is the most electoral college votes that a third party candidate ever received?
The answer:
Republican Theodore Roosevelt ran as the “Bull Moose Party” (Progressive Party) nominee in the 1912 election. Roosevelt won 27.4% of the popular vote and carried six states totaling 88 electoral votes. Overall, Roosevelt’s effort was the most successful third-party candidacy in American history. It was also the only third-party effort to finish higher than third in the popular votes and only the second to do so in electoral votes.
