American political dynamics are consistently shaped by evolving power structures and financial currents. For the contemporary Democratic Party, this involves facing challenges and, at times, being overshadowed by the growing influence of the Democratic Socialists of America (DSA), a phenomenon the established party appears largely unable to curb.
A Shifting Political Landscape
The United States has a rich history of political parties, ranging from the Federalists of 1789 and the Whig Party of the 1830s to more recent formations like the Libertarian Party (1971) and the Green Party (2001).
The Democratic Party, established in 1828, holds the distinction of being the longest-running major political party in American history.
Historically, smaller or lesser-known parties have played crucial roles, often pushing dominant parties to address specific issues or acting as a corrective force. An example is the Greenback Party, founded in 1874, which advocated for paper money in the late 19th century. While the Greenback Party itself dissolved, paper currency eventually replaced gold as the primary American medium of exchange. Similarly, the failings of the Whig Party paved the way for the emergence of the Republican Party.
Today, the long-standing dominance of the Democratic Party is encountering a new challenge from the Democratic Socialists of America. This modern iteration draws parallels to earlier socialist movements, such as the Socialist Party established in 1901, or even the American Communist Party, which began in 1919.
The Ascent of Democratic Socialists
DSA-affiliated candidates are actively campaigning nationwide, achieving notable successes, including New York Mayor Zohran Mamdani's victory.
This growing presence has prompted concern among some establishment Democrats, generating headlines reflecting alarm. For instance, Van Jones, a former adviser to President Barack Obama, recently voiced concerns that the DSA was "hijacking" the party's direction.
Conversely, other Democrats embrace the DSA, viewing the Democratic Party as a "big tent" that accommodates diverse viewpoints. Indeed, as has been observed, the DSA and the broader Democratic platform often align on significant policy matters, including the Green New Deal, tax reform, government-funded healthcare initiatives, and proposals related to police funding.
However, the fundamental reality is that the Democratic Party lacks direct control over the DSA. More significantly, it appears unable to prevent DSA members from identifying as "Democrats" and, in doing so, influencing the party's public image and ideological definition.
This shift stems from a crucial development approximately two decades ago: the financial lifeblood of politics—campaign funding—began to escape the once-tight grip of major political parties.
The Transformative Impact of Super PACs
In the era before 2010, political parties exercised considerable power over candidate selection. They achieved this through their control of fundraising, issuing endorsements, and allocating expenditures on behalf of candidates. This system ensured that candidates preferred, if not directly chosen, by the party leadership typically prevailed in Democratic primary elections.
That significant power has now largely diminished.
The current political landscape is characterized by the "Age of the Super PAC," where these independent expenditure-only committees can wield financial influence in a given race that often surpasses that of a major political party.
A pivotal change occurred in 2010, following the Supreme Court's decision in Citizens United v. Federal Election Commission. This ruling allowed Super PACs to raise and spend unlimited amounts of money to support or oppose a political candidate, provided they do not coordinate their activities directly with the candidate's campaign.
As a former chairman of the California Republican Party observed, prior to the Citizens United decision, the political parties themselves effectively functioned as the primary "Super PACs." This is no longer the case.
Empowering New Political Forces
Evidence of this transformation is widespread.
For example, Elizabeth Simons, daughter of the late hedge fund billionaire Jim Simons (who passed away in 2024) and co-inheritor of a $32.5 billion fortune with her stepmother Marilyn and two siblings, made a substantial donation of $250,000 to New Yorkers For Lower Costs. This organization positioned itself as the "official support PAC to elect Zohran Mamdani as Mayor of New York City," functioning as the main independent group backing his campaign.
In total, New Yorkers for Lower Costs reported nearly $2 million in contributions, which it then spent in support of Mamdani's mayoral bid. It is widely believed that his victory would have been unlikely without such significant financial backing.
Equally important, Mamdani, a recognized member of the DSA, was free to enter the New York mayoral race identifying as a Democrat. There are no legal provisions preventing such a candidacy. Similarly, Senator Bernie Sanders of Vermont, who identifies as a democratic socialist, has consistently run for office as a Democrat for many years.
Furthermore, consider the current state of the Democratic National Committee. It no longer serves as the central hub for Democratic political fundraising. The party's central organization is reportedly facing financial constraints, yet party strategists do not appear overly concerned. Instead, they anticipate relying heavily on Super PACs to fund campaigns in upcoming midterm elections.
This dynamic, a significant departure from previous eras, barely existed to its current extent before 2010 and shows no signs of abating in the near future.
This era, often termed the Age of the Super PAC, is being effectively leveraged by groups like the DSA. This development significantly challenges the longest-reigning major political party in American history, the Democratic Party, by redefining its internal power structures and future trajectory.
