Incumbent Republican Brian Fitzpatrick holds a lead in trader pricing for Pennsylvania’s 1st District House seat, reflecting his five-term incumbency, prior double-digit victories, and a modest Republican registration edge in the Bucks County-centered district. Recent internal polling has shown the race tightening to a statistical tie, prompting the Cook Political Report to move its rating from Likely to Lean Republican. Democratic challenger Bob Harvie has gained from heavy outside spending by House Majority PAC and the DCCC, high-profile endorsements including visits from House Minority Leader Hakeem Jeffries and Governor Josh Shapiro, and voter dissatisfaction with the Trump administration. Polling aggregates still place Fitzpatrick ahead by low single digits with three weeks remaining before the November 3 general election.
