The Democratic party's leftwing insurgency has breached the walls of a critical midwestern swing state, forcing a reckoning about the party's leadership and ideological direction ahead of the 2026 midterms and the 2028 presidential election. Abdul El-Sayed, a 41-year-old former public health official, defeated US congresswoman Haley Stevens to claim the party's nomination for the Senate in Michigan, delivering a knockout blow to the Democratic establishment.
El-Sayed's Progressive Agenda and Victory
El-Sayed campaigned on a boldly progressive agenda of universal healthcare, halting military aid to Israel, and sweeping campaign finance reform. In contrast, the moderate Stevens received $60m from outside groups, including $30m from the American Israel Public Affairs Committee (Aipac) and its affiliates. The victory, announced in the early hours of a Wednesday morning before The Spirit of Detroit, a landmark bronze statue in the city's downtown, saw El-Sayed channel boxing great Muhammad Ali, declaring, "We shook up the world."
Matt Duss, executive vice-president of the Center for International Policy and a former foreign policy adviser to Bernie Sanders, attributed El-Sayed's success to widespread dissatisfaction: "It's dissatisfaction with the status quo. It's dissatisfaction with the establishment. This is an anti-system moment. We see this not just in our country but in democracies around the world. Voters are fed up with an elite establishment that is simply not delivering for them, that doesn't feel their pain, that doesn't seem to know or care about their struggles, and that's part of why Abdul succeeded."
Historical Context of Leftwing Populism
The past decade of US politics has been dominated by Donald Trump's rightwing populism, but leftwing populism has been running on a parallel track since Sanders' 2016 presidential campaign. Duss noted, "The 2016 Sanders campaign was sort of the Big Bang for the rebirth of the progressive left in the United States. We've got a lot of others who joined Bernie. We've got a lot of great leaders on the progressive left now and are glad to have Abdul El-Sayed run."
Alexandria Ocasio-Cortez, a bartender and organiser for Sanders's 2016 campaign, pulled off a stunning upset in 2018 against an incumbent in New York's 14th district, becoming, at 29, the youngest woman ever to serve in the House of Representatives. She was joined by a group of progressives known as "the Squad." Sanders ran again in 2020, and though he lost to Joe Biden, his team influenced the Biden presidency's progressive agenda. The events of 2024, including Biden's abortive run, Kamala Harris's coronation, and Trump's return to power, exposed a chasm between party leadership and the grassroots.
Recent Progressive Victories and Driving Factors
Last November, Zohran Mamdani, a democratic socialist focused on affordability, beat establishment favourite Andrew Cuomo to become the first Muslim mayor of New York. He then helped three insurgent candidates win Democratic primary elections in New York. The "Mamdani effect" swept through Colorado, Illinois, Michigan, New Jersey, Pennsylvania, Washington state, Wisconsin, and Washington DC.
Driving factors include frustration with Trump, the cost of living, corporate money in politics, and the ongoing conflict in Gaza. Reuters/Ipsos polling showed Israel's favorability among Democrats plummeting from 59% in 2018 to just 22% in May 2026. In Michigan, which has the highest percentage of Arab Americans relative to population, El-Sayed accused Israel of committing genocide and built his campaign around ending unconditional US military aid to Israel, positioning himself directly against Stevens, who defended the US-Israel relationship and benefited from massive Aipac spending.
Watershed Moment for Progressives
El-Sayed's victory, coupled with wins for progressives Will Lawrence and Donavan McKinney in House races in Michigan, marked a watershed moment, challenging the myth that leftwing populists cannot win elections outside Democratic strongholds. Larry Jacobs, director of the Center for the Study of Politics and Governance at the University of Minnesota, perceives a general break within the party flowing from the "staleness" of its current leaders, Chuck Schumer and Hakeem Jeffries, both ardent supporters of Israel. "Gaza and Israel has become a lightning rod for all the other issues," he added. "There's a sense that the Democrats have been patsies in the face of Donald Trump. When Democrats say they want to fight back, they mean it. Trump has radicalised the Democratic party. This revolt within the party would not have happened without Donald Trump. He is provoking a kind of earthquake, raising lots of unsettling questions within the Democratic party - its direction, its leadership, its policy priorities, its beholdenness to big donors."
Trump has rattled old orthodoxies, prompting questions about whether the left can be as ambitious as the right's Project 2025. There is little appetite to return to the pre-Trump era, but rather to reimagine wealth redistribution, stronger unions, democratic reform, and a just foreign policy.
Maturation of the Progressive Movement
Joseph Geevarghese, executive director of Our Revolution, a group born out of Sanders' 2016 run, said: "You're seeing a maturation of the progressive movement. You're seeing the infrastructure that's been built over a decade come into play. There's a resonance of the message in reaction to the failed populism of the right but you're also seeing increased sophistication in the organisation of the left."
The rise of groups such as the Democratic Socialists of America (DSA) has occurred alongside a crisis of confidence within the centrist wing. Moderates are widely seen as timid incrementalists who lack ideas or superstars to compete with El-Sayed, Mamdani, and Ocasio-Cortez. Geevarghese commented: "Because some of their funding depends on corporate donors, moderates have to pull punches. They are not able to articulate the causes of people's problems. You've got progressives who are able to call out the corporate class and the corruption of our politics and how that affects people's standard of living."
Centrist Pushback and Future Challenges
Progressives warn that centrists are not likely to surrender power without a fight. Norman Solomon, director of RootsAction and executive director of the Institute for Public Accuracy, said: "One might say that hell has no fury like corporate Democrats scorned. I'm thrilled by the results in Michigan but at the same time I'm a bit apprehensive about the blowback from the powerful forces that have been accustomed to literally running the national Democratic party for many decades, arguably since the Democratic Leadership Council (DLC) was so successful at the beginning of the 1990s."
The DLC, founded by Al From, handpicked Bill Clinton in 1989 to steer the party toward the centre, creating the "Third Way" movement. From reflected this week: "We've been focusing on beating Republicans and the democratic socialists have been focused on beating us. We've got to fight back. We've got to make it harder for them." He insisted, "Our formula is the right formula. Obviously we're in a different world and you have to communicate it different and you'll need ideas that further the same underlying values, as we did, but they've got to be modern ideas, maybe different ideas because circumstances have changed. Our platform was for the 1990s, not for the 2030s, but the principles are the same. The democratic socialists want a different system. They don't want to further democratic values. You look at their platform: they want to get rid of the Senate, the presidency, the supreme court; they want ownership of business; they want to get rid of police; they don't want to fund the military. That isn't the historic Democratic party. It's not the party of Roosevelt that saved capitalism and saved democracy in the world in World War II. It's a different ideology, it's a different party."
El-Sayed's Path to November and Party Unity
The true test for El-Sayed, a Rhodes scholar, doctor, and son of Egyptian immigrants, will come in November when he faces Mike Rogers, a former Republican congressman, in a race that could determine the balance of power in the Senate. After an unusually rancorous campaign, El-Sayed urged "the things that unite us are so much bigger than the things that divide us," and Stevens quickly backed him. Progressives and moderates are likely to maintain an uneasy co-existence for the midterms, playing to their strengths against Republicans. Trump and House speaker Mike Johnson have sought to revive cold war-style panic by branding democratic socialists as "radical Marxists" and "godless communists."
Donna Brazile, a political strategist and former interim chair of the Democratic National Committee, said: "The question is, can two different wings of the same party function, unify and function as a governing majority if the Democrats win the majority? I contend that the answer is yes. We'll agree on very important matters like the economy, improving the lives of the American people, making things more affordable again and not focusing on vanity projects, so the extent that we're all running on the same message of affordability, the answer is yes."
But 2028 brings a time for choosing. The centrist group Third Way is planning a new $15m effort to discredit democratic socialism, the New York Times reported. Some Democrats argue progressives have won only a handful of races, while others believe the Michigan result means the leftwing lane just got wider. Geevarghese commented: "All of the electoral energy and enthusiasm is on the left and, at the end of the day, for a candidate to be viable in the 2028 presidential, they're going to have to articulate a full-throated economic populism. That's what's needed to make it through the primary and ultimately that's what's going to be needed to be the antidote to Donald Trump."
Speculation swirls around potential progressive standard-bearers. Mamdani, born outside the US, is not eligible to run. Congressman Ro Khanna of California, who campaigned for El-Sayed, is frequently mentioned, but the most intense focus is on Ocasio-Cortez, who is 36. Henry Olsen, a senior fellow at the Ethics and Public Policy Center, said: "If I were AOC's advisers, I would look her in the eye and say, 'Do you want to be president? If you want it to be president, the time is now. You will never have a better chance to own a lane that wants a leader.' One of the things we've seen across the world in the last decade is young female leaders captivating the left. Why not a 39-year-old AOC?"
