A Los Angeles Times article on the death of John Anderson blames his candidacy for Jimmy Carter’s loss in the 1980 Presidential Election.
These articles rarely, if ever, blame the losing major party candidates for the loss. A more thorough analysis would include the turnout. How many Jimmy Carter, Al Gore, and Hilary Clinton lukewarm supporters stayed away? I think poor turnout has far more to do with a major party candidate’s loss than anything else.
