James Walkinshaw represents a classic Washington insider-to-elected official trajectory, having spent a decade as chief of staff to his predecessor Gerry Connolly before winning local office on the Fairfax County Board of Supervisors. When Connolly endorsed him as his successor and subsequently died from cancer, Walkinshaw secured the Democratic nomination and won a special election in September 2025. As a Northern Virginia native and longtime congressional aide, he brings deep institutional knowledge of federal operations and strong ties to the region's political establishment to his freshman term in Congress.
