For over 200 years, the United States has been dominated by a two-party system, with the Democratic and Republican parties holding significant sway over the political landscape. This dominance has provided stability, but it has also led to widespread dissatisfaction among voters who feel their voices are not being heard. Third-party movements have attempted to challenge this system, yet success has been elusive. Similar to political controversies that arise in other areas, such as Scott Bessent’s divestment to avoid conflicts, third-party candidates often face significant hurdles when trying to break into the established political structure. Despite these challenges, the continued push for reform is evident, as seen in recent debates on social media regulation, including Meta’s decision to ditch fact-checkers. These ongoing shifts highlight the growing demand for change, much like the rising third-party movements aiming to reshape the U.S. political landscape. This article delves into the historical context, structural barriers, and potential pathways for third-party movements in the U.S.
A Two-Party Tradition
The Founding Fathers were wary of political factions. John Adams, for example, warned that “a division of the republic into two great parties… is to be dreaded as the great political evil.” Despite their concerns, the U.S. quickly developed a two-party system. Early third-party movements, such as the Liberty and Free Soil parties, played crucial roles in shaping political discourse, particularly on issues like slavery. The Republican Party itself began as a third-party movement in the 1850s, rising to prominence by addressing the moral and economic issues of the time.
However, since the mid-19th century, the Democratic and Republican parties have become deeply entrenched. While movements like the Progressive Party of Theodore Roosevelt in 1912 and Ross Perot’s Reform Party in 1992 garnered significant attention, they ultimately failed to disrupt the dominance of the two major parties. Despite these setbacks, third-party movements continue to emerge, driven by dissatisfaction with the existing political structure.
Structural Barriers to Third-Party Success
Several structural barriers make it difficult for third-party candidates to succeed in the U.S. political system.
1. First-Past-the-Post Electoral System
The U.S. employs a first-past-the-post (FPTP) electoral system, where the candidate with the most votes wins. This system discourages voters from supporting third-party candidates, as they are often seen as “spoilers” who may siphon votes away from major party candidates. Duverger’s Law explains how FPTP systems naturally gravitate toward two-party dominance, as voters prioritize electability over ideological alignment.
2. Ballot Access Challenges
Third-party candidates face significant hurdles in gaining ballot access. Each state has its own rules, many of which favor established parties. For example, in 2016, independent candidate Evan McMullin struggled to get on the ballot in multiple states, underscoring the systemic obstacles faced by outsiders.
3. The Electoral College
The Electoral College system further entrenches the two-party system by requiring a majority of electoral votes to win the presidency. This structure makes it nearly impossible for third-party candidates to compete unless they can achieve widespread national support, a challenging feat given the current political polarization.
4. Senate Filibuster and Legislative Gridlock
The Senate filibuster, which requires 60 votes to pass most legislation, disproportionately empowers smaller states and entrenched interests. This dynamic discourages systemic reforms that could benefit third-party movements, such as ranked-choice voting or proportional representation.

The Impact of Identity Politics and Polarization
The growing polarization in U.S. politics has created “megaidentities,” where race, religion, geography, and socioeconomic status closely align with party affiliation. This phenomenon has made political affiliation a core aspect of personal identity, further entrenching the two-party system. The urban-rural divide exacerbates this issue, as each region’s concerns are subsumed into broader partisan narratives, making it harder for third-party movements to gain traction.
Recent Efforts to Break the Duopoly
In recent years, movements like Andrew Yang’s Forward Party have sought to challenge the dominance of the two major parties. By positioning itself as a centrist alternative, the Forward Party aims to appeal to disillusioned Democrats and Republicans alike. Yang’s strategy includes collaborating with existing parties and focusing on pragmatic solutions, such as ranked-choice voting and open primaries.
Despite these efforts, third-party movements face significant challenges, including limited funding, media skepticism, and the entrenched loyalty of voters to the two major parties. Movements like Ross Perot’s Reform Party have struggled to maintain momentum after initial successes, showing the difficulty in sustaining third-party influence.
Pathways for Third-Party Success
For third-party movements to succeed, systemic reforms are essential:
1. Electoral Reforms
Ranked-choice voting could reduce the spoiler effect and encourage greater diversity in political representation. Proportional representation, used in many democracies, would allocate seats based on the percentage of votes received, giving third parties a fairer chance.
2. Reducing Polarization
Civic education and public dialogue can help bridge the divides that fuel identity-based partisanship. Grassroots movements and local initiatives can build trust and demonstrate the value of alternative political perspectives.
3. Media and Public Advocacy
Media outlets must provide balanced coverage of third-party candidates to counteract the perception that they are unelectable. Public advocacy campaigns can raise awareness about the benefits of a multiparty system.
Final Thoughts:
The rise of third-party movements in the U.S reflects growing dissatisfaction with the two-party system. While significant structural and cultural barriers remain, the increasing demand for ideological diversity and representation offers hope for change. Achieving this vision will require electoral reforms, grassroots advocacy, and a commitment to bridging the divides that polarize the nation. By addressing these challenges, the U.S. can pave the way for a more inclusive and dynamic democracy.
