The machine will churn no more. Nearly 80 years of top-down one-party rule in the United Auto Workers are coming to an end. Reformer Shawn Fain is set to be the winner in the runoff for the UAW presidency.

As of Thursday night, Fain had a 505-vote edge, 69,386 to 68,881, over incumbent Ray Curry of the Administration Caucus. Curry was appointed by the union’s executive board in 2021. There are around 600 unresolved challenged ballots. (This story will be updated with the final vote tally when we have it.)

“By now, the writing is on the wall: change is coming to the UAW,” said Fain. “You, the members, have already made history in this election, and we’re just getting started. It’s a new day in the UAW.”

It’s a stunning upset in one of the nation’s most storied unions. Once Fain’s victory is conclusive— after remaining challenged ballots are counted—he will join Secretary-Treasurer Margaret Mock, who ran on the Members United slate and won outright in the first round, and a majority of the International Executive Board, giving reformers control of the direction of the union. The UAW Members United slate won every race it challenged—a clear rebuke to the old guard.
