Chris Rabb secured the Democratic nomination for Pennsylvania’s 3rd congressional district after winning the May 2026 primary with 44.6 percent of the vote in an open-seat contest following Dwight Evans’ retirement. The Philadelphia-based district ranks among the nation’s most partisan, with forecasters rating it Solid or Safe Democratic and no Republican candidate on the November ballot. Rabb faces only independent Dennis Mahoney in the general election. Trader consensus reflects the district’s consistent Democratic margins exceeding 80 points in recent cycles and the absence of organized opposition. A personal or legal development involving Rabb remains the primary scenario that could alter the outcome before Election Day.
