In addition to the constitutionally established institutions of government institutions (the executive, legislative, and judicial branches), the American political system also consists of an organized group of linkage institutions that allow ordinary, unelected American citizens opportunities to interact and connect with government officials. There are four primary linkage institutions—political parties, interest groups, the media, and elections. 

Political Parties

Although political parties are not mentioned in the Constitution, and many of the Framers warned against forming them, the first parties were birthed shortly after the ratification of the Constitution and are a central part of the modern political system in the United States. Unlike other developed countries that use multi-party systems, the US utilizes a two-party system, where internal barriers prevent third parties from gaining enough support to win elections. The Democratic and Republican parties dominate the current two-party system in the US. Still, both have undergone significant changes since their creation in the nineteenth century due to critical elections and voter realignment. While third parties rarely pose significant challenges to major party candidates, they play a pivotal role in advancing issues that would otherwise be ignored by the other parties—and in some cases, third-party candidates have affected the outcome of presidential elections.

Interest Groups

Like political parties, interest groups are formed to influence government policymakers, but they don't directly recruit and run campaigns as parties do. While political parties represent millions of Americans by forming a platform stating beliefs on a wide range of issues, interest groups tend to have a more narrow focus, especially single-issue groups like the National Rifle Association (NRA) and the American Association of Retired Persons. The primary goal of political parties is to win elections and control the government, while the primary purpose of interest groups is to influence party candidates once they win office. Although interest groups are not mentioned in the Constitution, the Framers were well aware of the potential damage they could cause if left unregulated (📽️ Watch: AP Gov - Explaining Federalist #10).

The Media

The mass media in the context of American politics consists of broadcast and cable TV news, AM talk radio, news websites, social media platforms, and various forms of print media. Like political parties and interest groups, the media links people to the government by setting the public policy agenda—attempting to influence viewers, readers, and listeners by deciding what to report on and what to ignore. One recent development is the increasing significance of consumer-driven media in which news organizations (especially those that primarily operate online) produce stories that cater to viewers' ideological preferences—whether the information is substantive or not. Unlike parties and groups, the Constitution lays out specific protections for a free press within the 1st Amendment.   

Elections

Many people view voting in elections as the most important of all the linkage institutions. Elections provide Americans with the most direct opportunity to shape the system in which they're governed. While voting rights have expanded throughout American history, at the birth of the republic, many groups were denied suffrage—most notably persons of color and women. Over time, Congress and the Courts have expanded voting rights to historically marginalized groups, and nearly all Americans have the opportunity to vote in modern elections. Despite these expansions of suffrage, voter turnout in the United States continues to lag behind other developed countries, especially among younger voters. The modern electoral landscape now involves the increased use of professional consultants, massive campaign spending, and the integration of the Internet and social media throughout all phases of the campaign process.

Key Ideas

College Board: "Factors associated with political ideology, efficacy, structural barriers, and demographics influence the nature and degree of political participation."

In the US, political ideology, efficacy, structural barriers, and demographics all play a role in determining the nature and level of political participation. Political ideology refers to beliefs about government and power, while efficacy refers to belief in the ability to impact political outcomes. Structural barriers refer to systemic obstacles to political participation, and demographics such as age, race, income, etc., also influence participation.

College Board: "Political parties, interest groups, and social movements provide opportunities for participation and influence how people relate to government and policy-makers."

In the US, political parties, interest groups, and social movements provide avenues for citizen participation and shape the relationship between citizens and the government. Political parties bring together individuals with similar ideologies, interest groups represent specific interests, and social movements advocate for change. These groups offer opportunities for citizens to get involved through activities such as campaigning, lobbying, and activism, and help shape public policy by raising awareness and advocating for specific issues.

College Board: "The impact of federal policies on campaigning and electoral rules continues to be contested by both sides of the political spectrum."

The impact of federal policies on campaigning and electoral rules is a contentious issue in the US, with both political sides holding strong opinions. Some argue that federal policies ensure a fair and democratic process, while others argue that they interfere with states' rights and individual freedoms. The debate continues to be a central issue in American politics, and the extent of federal policies remains a subject of ongoing debate and negotiation.

College Board: "The various forms of media provide citizens with political information and influence the ways in which they participate politically."

The media plays a crucial role in shaping political information and participation in the US. Traditional news media, such as TV and newspapers, provide political information and shape public opinion. Social media provides real-time access and opportunities for political engagement. Entertainment media, including movies and TV shows, can also impact political attitudes and serve as a platform for activism. The media significantly impacts citizens' political information and participation in the US.
