Chris Rabb won the Democratic primary in Pennsylvania's 3rd Congressional District by nearly 15 points on May 19, 2026. This victory adds a progressive voice to Congress, as Rabb has been a vocal critic of U.S. military support for Israel and received endorsements from progressive figures such as Rashida Tlaib and Alexandria Ocasio-Cortez. The primary highlighted divisions within the Democratic Party, contrasting the progressive and moderate wings.
In the 7th Congressional District, Bob Brooks, a firefighters’ union chief, won his primary and will face Republican Rep. Ryan Mackenzie in the general election. Brooks campaigned on issues of affordability and corruption, securing more than double the support of his nearest competitor.
Rabb's victory is seen as a significant win for progressives, while Brooks' win reflects a unification of left and moderate Democrats in his district. The general election for both districts is anticipated to be competitive, with Brooks facing a tight race against Mackenzie, who previously flipped the seat from blue to red.
