In 2000, Three Candidates Appeared on Virtually All Ballots in the US

Essay

In 2000, three candidates appeared on virtually all ballots in the US Presidential election: George W.Bush, Al Gore and Ralph Nadar.Bush arguably won the election by 537 votes in Florida where Ralph Nadar received nearly 100,000 votes.It is often argued that Al Gore would have won the election had Ralph Nadar not been on the ballot in Florida.Discuss how this suggests that the social choice process the US uses to elect Presidents does not satisfy the Independence of Irrelevant Alternatives (IIA) assumption in Arrow's theorem.
