William Lawrence, a 36-year-old climate activist and co-founder of the Sunrise Movement, won Michigan’s 7th Congressional District Democratic primary on August 4, 2026, with 43.7% of the vote, setting up a competitive general election matchup against Republican incumbent Tom Barrett in November.
Lawrence defeated former U.S. Ambassador to Ukraine Bridget Brink, who received 28.8% of the vote, and retired Navy SEAL Matt Maasdam, who finished with 27.6%, according to official results. The three-way race centered on competing visions within the Democratic Party about electability and ideology in a swing district.
Lawrence’s campaign made opposition to artificial intelligence datacenters a central focus. According to his campaign manager Stevie O’Hanlon, Lawrence won with 49% of the vote in Mason, a town where a datacenter has been proposed, despite facing competition from two other candidates. Survey research by the polling firm Data for Progress found that 63% of U.S. voters supported pausing datacenter construction, including 66% of independents and 47% of Republicans.
The candidate rejected corporate PAC funding and ran largely on grassroots volunteer power. According to Maegan Houang, a volunteer who joined Lawrence’s campaign from Los Angeles, canvassers knocked on more than 100,000 doors leading up to Election Day, with roughly 80,000 of those visits occurring in June and July alone.
Lawrence secured high-profile endorsements from Senator Bernie Sanders, Representative Rashida Tlaib, and progressive U.S. Senate candidate Abdul El-Sayed. On the campaign trail, he emphasized support for universal healthcare, raising taxes on billionaires, and ending the war in Iran and arms sales to Israel. In his victory speech, he framed the win as a rejection of establishment influence, saying: “The people of Michigan’s 7th district sent a clear message: They are tired of Silicon Valley billionaires and D.C. insiders determining the future of our towns and our country.”
The primary victory carries national significance. Michigan’s 7th District, centered around Lansing, is one of just 18 House seats the Cook Political Report rates as a toss-up. The district voted for Republican Tom Barrett in 2024, but political conditions have shifted significantly. According to a recent poll by the House Majority PAC, Lawrence leads Barrett 49% to 47% in an initial head-to-head matchup.
Lawrence’s primary win reflects a broader pattern in 2026 Democratic primaries, where progressive candidates have gained traction in swing districts. Both Brink and Maasdam conceded gracefully and pledged support for Lawrence in the general election. Barrett, who assumed office in January 2025, acknowledged the result and said he would not underestimate his opponent, having seen the enthusiasm behind Lawrence’s grassroots movement. The general election campaign begins immediately, with Lawrence announcing that canvassing would resume in Mason on Saturday, August 8.
