In the TX-18 Democratic primary runoff set for May 28, traders heavily favor Harris County Attorney Christian Menefee at 74% implied probability over incumbent Rep. Al Green (24%), driven by Menefee's first-round lead of 36% to Green's 33% on March 5, which propelled him as the momentum frontrunner. Menefee's superior fundraising—over $1 million raised versus Green's under $300,000—and endorsements from Houston-area Democratic leaders, including former Mayor Sylvester Turner, have solidified his edge among progressive and younger voters seeking change from Green's two-decade tenure. Recent polls, such as a mid-April University of Houston survey showing Menefee ahead 52%-38%, reinforce this positioning amid low-key campaigning, while Green's congressional experience on Financial Services sustains his base support. Amanda Edwards and Gretchen Brown trail after weak first-round showings.
