Freshman Rep. Christian Menefee defeats longtime Rep. Al Green in the Democratic primary runoff for Texas’ 18th Congressional District, NBC News projects and Decision Desk HQ and other outlets report. The contest is an unusual matchup between two sitting Democratic members that occurs after Republican-led redistricting redraws the congressional map, reshaping districts in Houston-area and forcing Green and Menefee into the same seat. Under the previous district lines, the two lawmakers represented neighboring areas rather than competing directly in the same district. Menefee, 37, won a special election in January to fill the remainder of the late Rep. Sylvester Turner’s seat, and then advances after the primary runoff. Multiple outlets describe the race as one created by a Republican gerrymander, with some noting a broader pattern of Democratic generational and intra-party contests this election cycle. By winning the runoff, Menefee becomes the Democratic nominee for the 18th District and effectively ends Green’s run for the seat under the revised district boundaries.
