While the United States has had a two-party system for most of its history, it has not been uncommon to have separate, unaffiliated parties running for office, offering a unique perspective, alternative values, and a potential change of course. Third-party candidates have had some degree of success at the highest levels of government, most famously as President. This article takes a look at the most successful third-party Presidential candidates in U.S. history, exploring their campaigns and platforms, as well as their effects on the American political landscape.
Most Successful Third-Party Presidential Candidates
- Teddy Roosevelt (Bull Moose Party, 1912)
Teddy Roosevelt, a widely-loved former president of the United States, ran as a third-party candidate in 1912. Roosevelt felt betrayed by his former Republican party and ran on his own platform, under the Bull Moose Party. His platform included women’s suffrage, labor reform, trust-busting, and other progressive causes. Despite a campaign that was hounded by legal and political problems, Roosevelt was able to gain nearly 6 million votes, 27% of the total vote. He did cause a major problem for the Republicans, allowing Woodrow Wilson of the Democratic Party to win the Presidency.
- Ross Perot (Reform Party, 1992)
Billionaire business mogul Ross Perot made a historic bid for the Presidency in 1992 on the Reform Party ticket. His eclectic, populist campaign caused an unprecedented stir among the electorate. His platform focused on issues of debt reduction, budget reform, and balancing the budget. He secured nearly 19% of the popular vote, but due to the difficulty of his candidacy to gain Electoral College votes, he only received no electoral votes. Despite not winning the election, he did have a significant impact on the fortunes of the major candidates, most notably Bill Clinton.
- Ralph Nader (Green Party, 2000)
In 2000, consumer advocate and environmentalist Ralph Nader ran as the Green Party candidate for the Presidency. Nader ran on an unabashedly progressive platform, including practices such as taxing the wealthy more than the poor, a stronger social safety net, and increased environmental protections. He gained a sizable following among progressive voters, including young people and minority groups, and was able to take 2.7% of the popular vote. His efforts were criticized by some, claiming that he had taken votes away from the Democratic candidate, Al Gore, costing him the Presidency to George W. Bush.
The Legacy of Third-Party Candidates
Third-party candidates have played a valuable role in the evolution of American politics, bringing different perspectives and solutions to issues of the day, oftentimes outside the realm of the two major parties. Even when they are not successful in terms of direct election outcomes, they have often been able to influence the tone and face of American debates, leading to the adoption of their popular ideas. Moreover, many of the most successful third-party candidates have gone on to provide inspiring stories for those in the future seeking to bring about lasting change.
Third-party candidates have pushed the boundaries of American politics and challenged the status quo of a two-party system. Even when they have not been successful in terms of electoral outcomes, their efforts have often been integral in introducing new ideas and inspiring a new type of political discourse. From Teddy Roosevelt to Ross Perot to Ralph Nader, all of these candidates have shown that there are multiple pathways to creating positive and progressive change in the United States.
