Who's In the Race

Rep. Christian Menefee (D-TX) won the Democratic nomination in Texas's 18th District, Republican Ronald Whitfield won his party's primary, and the general election is set for November 3. ​

Menefee previously served as Harris County attorney from 2021 to 2025, where he was elected the youngest and first Black person to hold that office; his work there included litigation over voting rights and pollution. He won the May 26 Democratic primary runoff with about 69 percent of the vote over Green. Whitfield is a landscaping contractor who won the March 3 Republican primary with about 55 percent of the vote.

What They Stand For

Menefee has proposed guaranteeing healthcare access through Medicare for All, according to his campaign website. He has also supported protecting and strengthening public education; protecting abortion rights and reproductive healthcare; lowering costs for families; defending voting rights; and advancing environmental justice for communities overlooked on pollution, with investment in resilience, water systems, and the power grid, according to Community Impact.

The Money Behind the Race

Through June 30, Menefee had raised about $3.6 million and had about $156,000 in cash on hand, according to Federal Election Commission filings. No Republican fundraising figures were available for Whitfield.

Outside groups have spent about $7.1 million supporting Menefee, with Protect Progress the largest spender at about $6.5 million; Leaders We Deserve added about $287,000 and Project 218 about $200,000. Protect Progress alone accounts for about 91 percent of all outside spending in the race.
