Incumbent Rep. Christian Menefee's narrow 46%-44% edge over Rep. Al Green in the March 3 Democratic primary for Texas' 18th Congressional District has solidified trader consensus favoring Menefee at 75% implied probability for the May 26 runoff in this safely Democratic (D+61) seat reshaped by mid-decade redistricting. Menefee's incumbency stems from his January special election victory replacing the late Rep. Sylvester Turner, bolstering his strength in Harris County's district core (51.5%-38.2% lead), while Green dominates Fort Bend County but trails overall. A pre-primary UH Hobby School poll showed Menefee up 24 points, driving his frontrunner status amid low support for Amanda Edwards (7.7%) and Gretchen Brown (2%).
