Pennsylvania Gov. Josh Shapiro just passed his first major test of the midterms.

Bob Brooks, a Shapiro-endorsed firefighter union leader, will take on GOP Rep. Ryan Mackenzie in a key November battleground after clinching the Democratic nomination for Pennsylvania’s 7th District over a crowded field.

It’s a significant win for Shapiro, who helped recruit Brooks into the race as part of his aggressive push to help Democrats retake the House by flipping four competitive seats in Pennsylvania. A romp across the map could serve as a launchpad for the governor’s potential 2028 presidential campaign.

It’s also a boon to the Democratic Congressional Campaign Committee, which recently added Brooks to its “Red to Blue” program and boosted him with a pre-primary ad buy.
