The Democratic Socialists of America has endorsed a primary challenger against Rep. Shri Thanedar, D-Mich., escalating tensions within the Democratic Party as progressive groups target sitting members from their own flank.
Thanedar, who is seeking his third term representing Michigan's 13th Congressional District in the Detroit area, confirmed Monday that the national DSA had endorsed Donavan McKinney, a Michigan state lawmaker. The development marks another front in an ongoing battle between the far-left organization and establishment Democrats.
The congressman has drawn criticism from fellow socialists despite his progressive credentials. Thanedar previously renounced his own DSA membership in October 2023 following the Oct. 7 attacks on Israel.
"After the brutal terrorist attacks on Israel, which included the indiscriminate murder, rape, and kidnapping of innocent men, women, and children, I can no longer associate with an organization unwilling to call out terrorism in all its forms," Thanedar said at the time.
What the Left Is Saying
Progressive supporters of McKinney's candidacy argue that the challenge represents accountability rather than infighting. Sen. Bernie Sanders, I-Vt., a self-described democratic socialist, has backed McKinney alongside Rep. Rashida Tlaib, D-Mich.
Tlaib, who is herself a member of the DSA, pointed to policy disagreements with Thanedar as motivation for her endorsement. The incumbent's positions on various issues do not align with the values his district deserves, according to progressive supporters.
DSA leaders have framed their primary challenges as necessary to ensure elected officials fully represent working-class interests. The organization's national political director stated that the group prioritizes candidates who will consistently vote in line with DSA's platform on healthcare, housing, and economic justice.
The Detroit-area chapter of DSA had already endorsed McKinney before the national organization followed suit. Local members argued that Thanedar's record did not reflect sufficient commitment to socialist principles despite his voting pattern aligning with progressive causes most of the time.
What the Right Is Saying
Republicans have seized on the primary challenges as evidence that Democrats are moving further left and away from mainstream voters. The GOP has highlighted multiple DSA-backed victories against sitting Democrats as proof of an ideological shift within the party.
Rep. Henry Cuellar, D-Texas, one of the most vulnerable Democrats in upcoming elections, offered sharp criticism of the DSA's strategy.
"As a Democrat, I reject what the DSA is doing," Cuellar told Fox News. "I read their platform, and it is radical."
National Republican groups have used the primary results to fundraise, arguing that Democratic infighting weakens the party's general election prospects. GOP operatives argue that nominating more progressive candidates in traditionally competitive districts could hand Republicans victories they might not otherwise achieve.
Former Trump administration officials have pointed to these developments when discussing the future of the Republican Party's electoral strategy, suggesting that far-left primary wins create opportunities for Republican candidates in November.
What the Numbers Show
Thanedar won his 2022 primary with approximately 38% of the vote in a seven-candidate field. He went on to win the general election by 28 percentage points in the heavily Democratic district.
Several sitting House Democrats have already lost primaries to DSA-backed challengers this cycle. Rep. Dan Goldman, D-N.Y., and Rep. Adriano Espaillat, D-N.Y., both lost their seats to candidates with progressive endorsements. In Colorado, longtime Rep. Diane DeGette, a member of the Congressional Progressive Caucus, was unseated by Melat Kiros, who had DSA backing.
The DSA has endorsed more than 50 candidates across federal and state races this election cycle, according to the organization's public records. Of those with completed primaries, approximately 65% have won their contests.
The Bottom Line
The endorsement sets up a high-profile primary contest in one of America's most heavily Democratic districts. Thanedar's opposition to Trump on impeachment votes and his push for national reparations legislation have not shielded him from challenges within his own party.
November's elections will test whether the pattern of far-left primary victories translates into general election success or whether moderate Republicans can capitalize on Democratic Party divisions. Both parties are closely watching Michigan's 13th District as an indicator of broader electoral dynamics.
