do not meet petition requirements in which a certain number of voters must sign a petition for a third party or independent candidate to gain ballot access. In recent presidential elections, Ross Perot appeared on all 50 state ballots as an independent in 1992 and the candidate of the Reform Party in 1996. (Perot, a billionaire, was able to provide significant funds for his campaigns.) Patrick Buchanan appeared on all 50 state ballots in the 2000 election, largely on the basis of Perot's performance as the Reform Party's candidate four years prior. The Libertarian Party has appeared on the ballot in at least 46 states in every election since 1980, except for 1984 when David Bergland gained access in only 36 states. In 1980, 1992, 1996, 2016, and 2020 the party made the ballot in all 50 states and D.C. The Green Party gained access to 44 state ballots in 2000 but only 27 in 2004. The Constitution Party appeared on 42 state ballots in 2004. Ralph Nader, running as an independent in 2004, appeared on 34 state ballots. In 2008, Nader appeared on 45 state ballots and the D.C. ballot. For more information see ballot access laws. Debate rules Presidential debates between the nominees of the two major parties first occurred in 1960, then after three cycles without debates, took place again in 1976 and have happened in every election since. Third party or independent candidates have been included in these debates in only two cycles. Ronald Reagan and John Anderson debated in 1980, but incumbent President Carter refused to appear with Anderson, and Anderson was excluded from the subsequent debate between Reagan and Carter. Debates in other state and federal elections often exclude independent and third-party candidates, and the Supreme Court has upheld such tactics in several cases. The Commission on Presidential Debates (CPD) is a private company. Independent Ross Perot was included in all three of the debates with Republican George H. W. Bush and Democrat Bill Clinton in 1992, largely at the behest of the Bush campaign. His participation helped Perot climb from 7% before the debates to 19% on Election Day. Perot was excluded from the 1996 debates despite his strong showing four years prior. In 2000, revised debate access rules made it even harder for third-party candidates to gain access by stipulating that, besides being on enough state ballots to win an Electoral College
