(born 1938) Political pundit and three-time candidate for US president, Buchanan has been a nationally recognized political figure since the 1970s, as well as a consistent and outspoken advocate of social conservatism and economic protectionism. In 1992 he challenged incumbent President Bush for the Republican nomination, and was widely blamed for aggravating tensions between the conservative and moderate wings of the party with his harsh “family-values” rhetoric. In 1996 Buchanan shifted his focus to economics. His attacks on corporate greed and the twin economic threats of unrestricted trade and immigration struck a resonant chord with working-class Americans. He declared his candidacy for the 2000 presidential election as a Reform Party candidate.
