Attorney Jordan Herrera won the Democratic nomination in Missouri's newly redrawn 4th Congressional District, defeating Democratic socialist Hartzell Gray in a seven-way primary.
Herrera, an Air Force veteran and former Missouri assistant attorney general, secured the nomination, putting a more conventional Democrat on the November ballot against Republican Rep. Mark Alford in the GOP-leaning district.
The new 4th District takes in part of Kansas City before extending south through a broad swath of suburban and rural Missouri, a solidly GOP seat despite the map making Alford's district less Republican than it had been.
Herrera prevailed over Gray, who had framed his campaign as a left-wing challenge to the party establishment, after emerging as the clear financial leader in the Democratic field with over $250,000 in campaign donations through mid-July.
Gray had been endorsed by the Kansas City chapter of the Democratic Socialists of America, who praised his refusal to take money from corporations, developers, and lobbying groups, and pointed to his support for universal health care, tenant protections, and more progressive taxation.
Gray's campaign had received a significant boost from his appearance on a popular Twitch livestream, where he blasted "sell-out Democrats," and a subsequent appearance on another left-leaning online program, The Majority Report.
The general election will test whether the kind of coalition that powered Gray through a fractured Democratic primary can compete in a district intentionally drawn to favor Republicans.
