Patrick Joseph Buchanan (; born November 2, 1938) is an American paleoconservative political commentator, author, syndicated columnist, politician, and broadcaster. Buchanan was a senior advisor to U.S. Presidents Richard Nixon, Gerald Ford, and Ronald Reagan, and was an original host on CNNs Crossfire. He sought the Republican presidential nomination in 1992 and 1996. He ran on the Reform Party ticket in the 2000 presidential election.
He co-founded The American Conservative magazine and launched a foundation named The American Cause. He has been published in Human Events, National Review, The Nation, and Rolling Stone. He was a political commentator on the MSNBC cable network, including the show Morning Joe until February 2012, and now appears on Fox News. Buchanan has been a regular on The McLaughlin Group since the 1980s. His political positions can generally be described as paleoconservative, and many of his views, particularly his opposition to American imperialism and the managerial state, echo those of the Old Right Republicans of the first half of the 20th century.
