There have been three notable third-party candidates for U.S. President in the past three decades: Ralph Nader, H. Ross Perot and John B. Anderson. The last of the three mounted a spirited campaign as alternative to Jimmy Carter and Ronald Reagan in 1980. He came away with almost 7% of the vote. A Republican from Illinois, he was a member of what is now an all-but-extinct breed: a cerebral and compassionate conservative who was disgusted by the mounting dirtiness of right-wing politics and the encroachment of an intolerant strain of religion on the political process. Anderson turned 89 this year and in the most recent Presidential election supported Barack Obama.
