Mexico Commissioner of Public Lands Aubrey Dunn Jr. switched his party registration from Republican to Libertarian and subsequently announced he would run as the Libertarian nominee for the Senate election in New Mexico. Dunn was the first Libertarian in a partisan statewide office and was the highest ever official from the Libertarian Party until US Representative Justin Amash switched his party registration from independent to Libertarian on April 29, 2020. In December 2020, Maine House of Representatives member John Andrews changed his party registration to Libertarian after winning re-election as a Republican. There have also been a number of politicians who joined the Libertarian Party, sometimes only briefly, after having left office, including former New Mexico Governor Gary Johnson, former Massachusetts Governor William Weld, former Rhode Island Governor Lincoln Chafee, former Alaska United States Senator Mike Gravel, former Georgia Congressman Bob Barr, and former Texas Congressman Ron Paul. Presidential ballot access The Libertarian Party has placed a presidential candidate on the ballot in all 50 states, as well as D. C., six times: 1980, 1992, 1996, 2000, 2016, and 2020. That level of ballot access has only been achieved by a third-party candidate four other times (John Anderson in 1980, Lenora Fulani in 1988, and Ross Perot in 1992 and 1996.) Although the territory of Guam has no electoral votes, it began holding presidential preference elections in 1980. The Libertarian Party presidential candidate has appeared on the ballot in Guam in every election from 1980 through 2020, except for 2016. Anderson and Fulani were also on the ballot in Guam. The following is a table comparison of ballot status for the Libertarian Party presidential nominee from 1972 to 2020. In some instances the candidate appeared on the ballot as an independent. Political positions The Libertarian Party supports laissez-faire capitalism and the abolition of the modern welfare state. It adopts pro-civil liberties and pro-cultural liberal approaches to cultural and social issues. Paul H. Rubin, professor of law and economics at Emory University, believes that while liberal Democrats generally seek to control economic activities and conservative Republicans generally seek to control consumption activities such as sexual behavior, abortion and so on, the Libertarian Party is the largest political party in the United States that advocates few or no regulations in what he deems "social" and "economic" issues.
