Based on the latest wave of Democratic primary results, it’s looking more likely that the hard-left “resistance” faction of the Democratic Party, which was muted in the aftermath of the 2024 election, is reasserting itself in a consequential way — especially in the deep-blue cities that make up much of the party’s voting base. 

Democratic socialist Zohran Mamdani’s come-from-behind victory in the New York City mayor’s primary was a major wake-up-call for party leadership. His success came after a surge of progressive discontent with the Democratic establishment, a sentiment fueled by the Trump administration’s aggressive (and at times, unlawful) deportation push, the imposition of tariffs and the general sense that party leaders in Washington weren’t doing everything they could to oppose President Donald Trump’s polarizing policies.

The reason the Democratic Party brand is polling at historic lows is because a sizable share of younger, progressive voters are expressing their discontent with their own party leadership — even as most still plan to vote Democratic in a general election. We’re seeing the growth of the left-wing faction within the party, in real time. 

The fact that Mamdani’s radical views on the economy, crime and antisemitism did little to dissuade a critical mass of rank-and-file Democrats is a sign of the changing mood of the party. 

That same dynamic that drove New York City Democrats was apparent in the first round of results in Seattle’s local primaries Tuesday night. 

In the early returns from the city’s all-party primary, moderate incumbents — serving as mayor, city attorney and council president — were all trailing left-wing challengers. The moderate city officials were elected in 2021, largely as a backlash to the crime, homelessness and disorder in the city under progressive leaders. 

In the most high-profile race, Mayor Bruce Harrell is trailing progressive activist Katie Wilson, 46-45%. “Wilson’s campaign generated new excitement when Zohran Mamdani, a Democratic Socialist, won the mayoral primary in New York City in June,” Seattle’s NPR affiliate reported. 

In Washington, the primary results aren’t determinative; the top two vote-getters compete against each other in the general election. But they suggest moderates will be facing an uphill battle against left-wing insurgents.

The same dynamic is at play in Minneapolis, where conventionally liberal Mayor Jacob Frey decisively lost the Democratic Party endorsement to a democratic socialist state senator, Omar Fateh. 

Frey still can win reelection in November, when all candidates appear on the general election ballot regardless of party, but the rebuke from the Democratic delegates is another sign that the party is facing a revolt from its left-wing activists.

Right now, this looks more like the party of Bernie Sanders, Mamdani and AOC. Those are the candidates that are energizing the grassroots and driving social media engagement— especially when it comes to the party’s urban voters. 

These results send a strong signal that the Democratic Party vibes have shifted. In the first few months of Trump’s second term, party leaders were desperately trying to distance themselves from the ideological baggage of the left. More recently, they’re coming to terms with the possibility that the left is taking over the party.
