Chris Rabb, a self-described democratic socialist and state representative from Philadelphia, secured his path to Congress when he won Pennsylvania’s 3rd Congressional District Democratic primary on May 19, 2026, with 45% of the vote, and will face no Republican opponent in November’s general election.
Rabb finished 15 percentage points ahead of his closest competitor, state Senator Sharif Street, who garnered less than 30% of the vote. Third-place finisher Dr. Ala Stanford, who had received endorsements from retiring incumbent U.S. Rep. Dwight Evans and backing from a left-leaning political action committee that spent $3.5 million, fell further behind. No Republican sought the GOP nomination in the district, meaning Rabb’s primary victory effectively secured his seat in Congress.
The progressive legislator’s upset victory defied the Philadelphia Democratic establishment. Mayor Cherelle Parker and members of Pennsylvania’s U.S. House delegation had endorsed Street, while building trades unions contributed more than $600,000 to his campaign. Rabb, by contrast, was propelled by grassroots organizing from local progressive groups including the Philadelphia Democratic Socialists of America and the Working Families Party. He received high-profile endorsements from U.S. Rep. Alexandria Ocasio-Cortez and other members of “the squad,” including U.S. Reps. Ilhan Omar, Ro Khanna, and Jamie Raskin.
Rabb’s campaign centered on direct critiques of both the Republican establishment and his own party’s leadership. He argued that Democrats had become too beholden to donors rather than voters, and he positioned himself as a fighter willing to take bold action against what he called a rigged economy and political system. In his victory speech, Rabb declared: “I have been critiqued along this campaign for being too radical, too bold. They ain’t seen nothing yet.”
The race revealed sharp divides on foreign policy, particularly regarding the war in Gaza. Rabb was the only candidate to call for an end to U.S. aid to Israel and the only one using the term “genocide” to describe the conflict. Stanford had likened using the word “genocide” to “using the N-word,” a stance that alienated some voters seeking a more forceful progressive voice.
Part of a Broader Progressive Wave
Rabb’s victory is one of the most significant among a constellation of DSA-backed candidates winning Democratic primaries across the country in 2026. According to the Washington Post, DSA leaders reported that the 2026 primaries have brought wins “beyond what they dared to hope for.” In New York City, twelve of thirteen DSA-backed candidates won their races, including three incumbents. In Michigan, progressive and DSA-backed candidates made substantial gains in early August primaries, with support from the Working Families Party and the United Auto Workers.
Adam Green, co-founder of the Progressive Change Campaign Committee, said Rabb’s win sent a message about what voters want: “They want someone who knows what they stand for and is ready to fight, whether it’s fighting Donald Trump now or fighting an economy and political system rigged for billionaires in years ahead.”
Some Democratic strategists cautioned that the progressive surge could pose challenges for the party. However, Pittsburgh-based Democratic strategist Mike Mikus noted that in 2026, broader economic conditions favor any candidate promising change. “Regardless of who we nominate, gas prices are still too high, grocery prices are too high and people generally think the economy is not in a good place,” Mikus said. “And voters will vote for change.”
Rabb will replace Dwight Evans, who did not seek reelection. The 55-year-old has served five terms in the Pennsylvania House of Representatives representing Northwest Philadelphia, where he built a reputation as an outspoken advocate for racial justice, economic equity, and government reform. He is a Penn alumnus who previously worked as an aide to U.S. Sen. Carol Moseley Braun and served on the White House Conference on Small Business during the Clinton administration.
