Michigan Rep. Shri Thanedar lost his Democratic primary Tuesday to a Democratic Socialists of America-backed state lawmaker, the latest in a string of far-left insurgents toppling party incumbents across the country.
State Rep. Donavan McKinney, 32, defeated Thanedar in Michigan's 13th Congressional District, which covers a large swath of Detroit. McKinney won with 52% of the vote, ending Thanedar's bid for a third term despite the incumbent's massive financial edge and the backing of House Minority Leader Hakeem Jeffries.
The result is more than a local upset. It marks the clearest signal yet that the Democratic Socialists of America and its progressive allies are building real power inside the Democratic Party, not at the margins, but in primaries that decide who goes to Congress. Thanedar joins a growing list of Democratic incumbents swept aside by insurgent challengers in New York, Colorado, and now Michigan.
Thanedar, an India-born entrepreneur who co-founded an Ann Arbor-based chemical testing lab in 2010, built a personal fortune in the tens of millions of dollars. He used that wealth to self-fund his original run for the seat and entered this cycle with a commanding $4.7 million cash advantage over McKinney.
None of it mattered. Prediction markets priced McKinney at roughly 87% to win the day before the vote. Thanedar's own colleagues largely abandoned him, and even the incumbent conceded his standing within the party was weak.
"It's not like a high school. I'm not trying to be the most popular member of Congress," Thanedar told reporters during the campaign, according to Breitbart. The voters of Detroit's 13th District apparently agreed he was not popular, and decided to act on it.
McKinney consolidated opposition in a way past challengers never managed. Unlike previous cycles, when the anti-Thanedar vote split among multiple candidates, McKinney had a clear one-on-one matchup. He also carried endorsements from some of the most prominent progressive voices in Congress: Rashida Tlaib, Ilhan Omar, Ayanna Pressley, and Sen. Bernie Sanders all lined up behind him.
Thanedar, by contrast, leaned on Jeffries and the Democratic establishment, a coalition that proved insufficient in a district where the activist left holds real sway. The pattern mirrors other recent Democratic primary upheavals in which incumbents discovered too late that party leadership backing could not shield them from their own base.
McKinney entered the primary in April 2025 and framed the race as a fight between working-class Detroit and a wealthy interloper. His campaign message was blunt.
Fox News reported McKinney's pitch to voters directly:
"People like our congressman, Shri Thanedar, are the problem. A multimillionaire who spent millions to buy a seat in Congress, who has more in common with Donald Trump and Elon Musk than people like us."
That line, comparing a Democratic incumbent to Trump and Musk, tells you everything about the ideological lane McKinney occupies. He ran as a DSA socialist, and he won as one.
The race also carried a racial dimension. When Thanedar won his seat in 2022, it left Detroit, a city that is nearly 80% Black, without Black representation in Congress for the first time since 1955. McKinney's victory restores that representation to a majority-minority district, a fact that AP News noted carried weight with local voters.
Sensing the challenge from his left flank, Thanedar pushed articles of impeachment against President Trump around the same time McKinney entered the race in April 2025. The move looked like a transparent attempt to shore up progressive credentials, and it failed to change the trajectory of the contest.
"There's nobody fighting harder than me against Trump," Thanedar insisted during the campaign. But McKinney and his backers argued Thanedar's anti-Trump posture was a late-game conversion, not a genuine commitment. The incumbent had broken with the DSA in October 2023 over his support for Israel following the October 7 terror attacks, a split that cost him dearly with the activist left.
Thanedar's record also carried baggage that had nothing to do with ideology. Roughly 170 dogs and dozens of monkeys were abandoned at a facility he owned, a fact that dogged him throughout the campaign. He also faced scrutiny over billboards featuring his own image that were paid for with taxpayer money through his congressional office. Neither controversy helped an incumbent already struggling to connect with his district.
The broader trend should concern anyone watching the Democratic Party's internal dynamics. Thanedar is not the only incumbent to fall. Reps. Adriano Espaillat and Dan Goldman, both New York Democrats, and longtime Colorado Rep. Diana DeGette have all been defeated by insurgent challengers. The DSA and its allied organizations, including Justice Democrats, the group aligned with the progressive "Squad", are systematically targeting vulnerable incumbents and winning.
This is the same faction of the Democratic Party that has generated repeated controversies among its Squad-aligned members. And it is gaining seats, not losing them.
McKinney will face Republican T.P. Nykoriak in the November general election. Michigan's 13th District, anchored in Detroit, is overwhelmingly Democratic, and Nykoriak faces steep odds. The real election, for all practical purposes, happened Tuesday.
That means a DSA-endorsed socialist is almost certainly heading to Congress. He will join a caucus that already includes Tlaib and the remaining Squad members, a bloc that has shown it can disrupt party unity on major legislation and pull Democratic leadership further left on spending, foreign policy, and law enforcement.
For Republicans, the Democratic Party's leftward lurch in its primaries presents both an opportunity and a warning. The opportunity is obvious: every DSA-backed nominee gives GOP candidates a clearer contrast in swing districts. The warning is subtler. In safe blue seats like Michigan's 13th, these candidates do not need to moderate. They arrive in Washington with no incentive to compromise and every incentive to push the party's center of gravity further from the mainstream.
President Trump has warned repeatedly that the Democratic Party is drifting toward socialism. Primary nights like Tuesday suggest the drift has become a march, and the marchers are winning.
When a party's own voters keep firing its incumbents and replacing them with candidates endorsed by the Democratic Socialists of America, it is no longer a fringe movement. It is the direction of the party, and voters everywhere should pay attention to where that road leads.
