Michigan Democrats are voting in a primary that pits establishment-backed Rep. Haley Stevens against progressive candidate Abdul El-Sayed for the party's US Senate nomination, in a contest the author frames as a test of whether the party can resist a leftward "socialist" surge. The winner will face former Republican Congressman Mike Rogers in November for the seat being vacated by retiring Senator Gary Peters, with polling and prediction markets suggesting the more progressive wing has the upper hand.

El-Sayed has raised a substantial $14.5 million and campaigns on policies including abolishing ICE, imposing an arms embargo on Israel and reforming the Supreme Court, while Stevens represents the party's more moderate establishment lane. Mallory McMorrow remains on the ballot despite having suspended her campaign, though the race has effectively become a two-way contest between Stevens and El-Sayed.
