Matt Van Epps, endorsed by Donald Trump, and Democratic Rep. Aftyn Behn won their respective primaries Tuesday. They will compete in a December special election for a vacant U.S. House seat in Tennessee's 7th Congressional District. Van Epps, a former governor's administration official, credits Trump's endorsement for his win. Behn, a social worker, highlighted her victory as a triumph for grassroots organizing. The election could serve as a gauge for Trump's agenda's appeal, particularly in suburban areas of the safely Republican-drawn district.
