XI. Historical Context

The district was held by Republicans for 60 of 66 years after its re-creation in 1952, including Joel Broyhill (1953–1974) and Frank Wolf (1981–2014). Barbara Comstock succeeded Wolf in 2014. Jennifer Wexton (D) defeated Comstock in the 2018 midterms, becoming only the second Democrat to win the district. Wexton did not seek re-election in 2024 due to progressive supranuclear palsy diagnosis. Subramanyam won the open seat in 2024 (Wikipedia).
