The battle between the two souls of the Democratic Party — the centrist faction and the progressive wing — erupted into a brutal skirmish in Michigan on Sunday, just two days before the midterm legislative elections. The confrontation occurred when Democratic Congresswoman Haley Stevens, who lost the state primary to Abdul El‑Sayed (who hopes to become the first Muslim senator in U.S. history with a platform to the left of the party), took part in a campaign event at a Detroit church alongside Republican Senate candidate Mike Rogers.

The contest between Rogers and El‑Sayed is one of the most consequential of these midterms; Democrats are pinning much of their hopes of retaking control of the Senate — currently held by the Republicans with 53 seats to 47 — on it. In Michigan’s primaries, voters backed the progressive option represented by El‑Sayed, a trend that has been gaining ground on the U.S. left in the tradition of Senator Bernie Sanders and Congresswoman Alexandria Ocasio‑Cortez, fueled by the victories of New York mayor Zohran Mamdani and by the nationwide consolidation of the Democratic Socialists of America (DSA, a group El‑Sayed is close to but not a member of).

Stevens, a member of the U.S. House of Representatives in Washington, was the establishment candidate. And U.S. President Donald Trump enthusiastically welcomed her decision to switch sides in a message praising her “bravery.”

El‑Sayed, who has been the target of virulent Islamophobic attacks from Republicans, is a physician who supports policies such as expanding health coverage and has declared himself an opponent of the oligarchy that, he says, has gained even more power since Trump returned to office.

After facing each other in the primaries, the two politicians — soldiers on a symbolic battlefield over the party’s future — have deepened their differences. El‑Sayed asked Stevens not to appear with him at another church event on Sunday that was intended to symbolize unity between progressives and moderates within Michigan’s Democratic Party.

In addition to appearing at a rival rally for Republican candidate Rogers, Stevens returned the friendly fire by explicitly endorsing El‑Sayed’s opponent in a message on X. “Our Democratic nominee for the U.S. Senate, Abdul, said I was no longer welcome in his campaign and that I should away,” the congresswoman said in a video posted on the social network owned by Elon Musk. “And he’s right. And that’s why I am endorsing Mike Rogers for the United States Senate.”

“I don’t think about Stevens”

“At the end of the day I actually don’t think about Haley Stevens,” El‑Sayed told reporters in Detroit on Sunday amid the drama. “None of this matters.” The candidate cited the “hatred” from his rival, from Rogers, from Trump, and from Vice President J. D. Vance, and stressed the need to improve “healthcare,” public education and “the right to form unions” — all “principles,” he said, that he defends.

Such dramatic party switches are uncommon in U.S. politics. Even more so two days before a ballot in which Americans will vote to renew all 435 seats in the House of Representatives and 35 Senate seats. The viability of the second half of Trump’s presidency is also at stake.

That said, the campaign has seen isolated cases of defections similar to those by Karl Rove, a prominent Republican from the George W. Bush era, who announced his backing for Democrat James Talarico over his rival, the controversial Ken Paxton — handpicked by Trump — in their battle for the Senate seat representing Texas.

Trump greeted the news of Stevens’ change of heart with enthusiasm. “Wow, this is BIG!” he wrote on his social network, Truth, saying that “her following is huge,” and that “the level of respect from the People of Michigan, especially our African American and Jewish populations, is virtually unparalleled.”

“Haley said what few people are willing to say. She showed great and almost unprecedented loyalty to the Great People of Michigan with what she did. It’s a thing called bravery, and few people have it like just displayed by Congresswoman Haley Stevens!” Trump added in his post.

Several staffers from Stevens’ Washington congressional office resigned on Sunday in response to their boss’s decision.
