The United States is a Constitutional Republic with a two-political party system, meaning there are two major parties that run politics for the entire nation. These two political parties are called the Democratic Party and the Republican Party. This party system works by giving voters a choice between candidates from those two factions, who often have competing ideologies, policy positions, and candidates. 

Of course, just because a country has a two-political party system, it doesn’t mean that there aren’t alternate choices through third-party candidates. However, it’s been historically difficult for third-party candidates to gain enough traction to win an election and effect real change in American politics. However, we will explore why it’s important for these candidates to run more races as we analyze how the two-party system works. 

How the Two-Party System Works

The current two-party system in the United States is a political arrangement in which two major political parties, the Democrats and the Republicans, dominate the political landscape. This system has evolved over time and is not mandated by the U.S. Constitution. However, it has become deeply entrenched in American politics due to various historical, social, and institutional factors.

Here's an overview of how the two-party system works in the U.S.:

  • Political parties and their platforms: The Democratic and Republican parties have distinct policy platforms and ideologies that they use to appeal to different segments of the electorate. The Democrats generally lean more towards progressive and liberal policies with more government oversight, while the Republicans typically favor conservative and right-leaning policies with a smaller government.

  • Electoral system: The U.S. electoral system, particularly the "first-past-the-post" or "winner-takes-all" system, encourages a two-party system. In this system, the candidate who receives the most votes in a given district or state wins the election, and there is no proportional representation for other parties. This discourages smaller parties from gaining traction and makes it difficult for them to win elections without the right support.

  • Primaries and caucuses: In the lead-up to general elections, both parties hold primaries and caucuses to select their candidates for various offices, including the presidency. These events allow party members and supporters to have a say in the nomination process and often serve to reinforce the two-party system, technically giving the partis more power than the voters in some circumstances. 

  • General elections: During general elections, voters choose between candidates from the Democratic and Republican parties, as well as any independent or third-party candidates on the ballot. The two-party system is reinforced as most voters and media coverage focus on the major parties' candidates as many independent candidates lack strong support. 

  • Government formation: The winning party in a general election typically forms the government at the federal, state, and local levels. The president, governors, and mayors often come from one of the two major parties, reinforcing their dominance in the political system. However, independent and third-party candidates have been able to win most major offices in the past. 

  • Partisan polarization: Over time, the two major parties have become increasingly polarized, with Democrats and Republicans moving further apart on key issues. This polarization can make it difficult for third parties or independent candidates to find a place in the political spectrum, further entrenching the two-party system. When an independent candidate is able to win office, though, it does give them more power to sway a close division. 

While the two-party system has been a longstanding feature of American politics, it has also been criticized for limiting political diversity and discouraging compromise. Critics argue that it may not always represent the full range of political views held by the U.S. population and can lead to partisan gridlock in government. Many believe that the country would be better off with more parties or more independent candidates winning elections.

The Democratic Party

The Democratic Party has historically been known as the party of the people. It is generally considered to be the more progressive and liberal of the major parties in the United States. The roots of the Democratic party can be traced back to the Democratic-Republican Party, which was founded in the 1790s by Thomas Jefferson and James Madison. The modern Democratic Party was formed in 1828, under the leadership of President Andrew Jackson.

The Democratic Party tends to advocate for social, individual, and environmental protections, like welfare programs, environmental protection, civil rights, and labor rights. The reason the Democratic Party is referred to as the party of the people is that it has supported programs, like Social Security, Medicare, and The Affordable Care Act. They also support organized labor and workers’ rights.

In recent years, the Democratic Party has also become increasingly vocal in its support for environmental protection and climate change, as well as for criminal justice reform and immigration reform. The party is also associated with support for expanding access to healthcare, increasing taxes on the wealthy, and reducing income inequality.

The Democratic Party has had a number of notable leaders throughout its history, including Franklin D. Roosevelt, John F. Kennedy, and Barack Obama. Today, the party is led by President Joe Biden and Vice President Kamala Harris, along with a range of elected officials at the local, state, and national levels.

The Republican Party

The Republican Party, sometimes referred to as the GOP (Grand Old Party), in the United States is considered to be the more conservative and traditional political party. It tends to push traditional family values and business, and an overall small government that limits how much it interferes with citizens. 

The Republican Party was formed as an anti-slavery party in 1854. It was made up of a group of anti-slavery activists and former members of the Whig Party, the American Party, and the Democratic Party. The Republican party was formed in response to the passage of the Kansas-Nebraska Act, which allowed for the expansion of slavery into new territories.

The Republican Party advocates for policies such as lower taxes and reduced government spending. They also advocate for a more limited role for the federal government in many areas, including healthcare and education. The party is also associated with support for a strong national defense and a strict interpretation of the Constitution.

The Republican Party has had a number of notable leaders throughout its history, including Abraham Lincoln, Theodore Roosevelt, and Ronald Reagan. Today, the party is led by a range of elected officials at the local, state, and national levels, including Senate Minority Leader Mitch McConnell and the Speaker of the House Kevin McCarthy.

Drawbacks of a Two-Party Political System

While the two major party system in the US is the dominant party system, it’s been criticized for its limited choices, polarization, lack of representation, and voter disillusionment. This is because, with only two main parties, voters are limited in their choices for political candidates, and while there may be third-party candidates on the ballot, voting for a third-party candidate can often make voters feel like they’re throwing their votes away in this type of limited party system.

Additionally, the two-party system can lead to both parties becoming extreme in their views and refusing to compromise. This can make it increasingly difficult to develop and pass good government policies. In fact, this typically leads to a lack of policies being made to help the citizens as both parties have selfish motives. 

Money is also a major issue with the two-party system because the two parties are so much better funded than the others. The major parties often receive the most media attention and donations, making it difficult to impossible for third-party candidates to raise enough money for their campaigns so that they can be considered serious contenders in the elections. It’s vitally important for independent candidates to get as much support as they can. 

The US Needs Third-Party Political Candidates for Diversification and New Ideas

The United States has been controlled by a two-party system almost since its inception, meaning that while there have been other parties, two parties have almost always managed to control the political power. Early in the country’s history, it was the Federalist Party and the Democratic-Republican Party that dominated the political party system. 

Later, it was the Whigs and the Democratic Party. Of course, there have been a few more political parties in the United State’s history, including the Liberty Party, The Free Soil Party, which was a split from the Liberty Party, and the American Party, which was comprised of ex-Whigs who were against Catholicism and immigration.

Today, the country also has numerous third parties, including the Green Party, Libertarian Party, and Constitution Party, which was formerly known as The American Taxpayers Party, the Independent Party, Socialist Party USA, and the Reform Party. While it has been difficult for these parties to gain traction in a legitimate run at being the third major party, some have been successful in getting candidates on the ballot and winning important elections. 

In 2000 and 2004, Ralph Nadar appeared as a Green Party candidate on the presidential ballot, and he garnered more than 2 million votes in 2000. Prior to Ralph Nadar, there was Ross Perot, which was nominated by the Reform Party in 1992. he ran on a platform of reducing the national deficit and garnered more than 19 percent of the vote. In fact, his platform was so popular, that Bill Clinton had to address the US deficit, or he risked his political career.

The Need For Candidates From Other Parties

Third-party candidates have the potential to add greater political diversity, increase voter participation and offer greater representation while helping to create positive changes in the political landscape. They can also help increase accountability and help increase the success of policy negotiations. It’s important to find as many third-party or independent candidates as possible to bring the focus away from two selfish parties and back to the actual citizens of the country.

Two-Party System Frequently Asked Questions (FAQs)

When did the two-party system begin in the United States?

The two political party system in the USA started in the 1790s with the creation of the Federalist Party, which favored a strong central government and close ties with Great Britain, and the Democratic-Republican Party, which favored states' rights and closer ties with France.

What is the difference between a two-party and a multi-party system?

A two-party system is a political system in which two major political parties dominate the government. In this party system, most elected officials belong to one of the two major parties, and other third parties have little chance of winning elections or gaining significant political power.

A multi-party system is a political party system in which several political parties compete for political power and representation in the government. This means that multiple parties have the potential to win elections and hold significant political power. The main benefit of a multi-party system is that these parties will represent a broad range of political ideologies and perspectives that could be incorporated into various policies.

What are the three primary features of a two-party system?

The three main features of a two-party system include dominance, favoritism, and coalition.

  1. Dominance – The two primary political parties dominate the political landscape and hold the majority of the political power. They have well-established organizational structures, well-known names, and established ways to successfully raise funds.

  2. Favoritism – In political elections, the two major parties are favored over any other political party, and the candidates are often pitted against each other in winner-take-all election scenarios.

  3. Broad Coalitions – Having a two-party system means that both parties must have a wide range of interests in order to appeal to the most voters. To achieve this, both political parties' views may overlap.
