McManus: The third-party wild card

American voters have fired two modern presidents after just one term, Jimmy Carter in 1980 and George H.W. Bush in 1992. Both suffered because the economy was in poor shape, and both faced disaffection within their own parties. But there was another thing those candidates had in common: They both faced relatively strong third-party candidates in the November election.
