Mandela Barnes dropped out of Wisconsin's Democratic primary for governor on Thursday, and the party that once called him a rising star is now staring at a socialist frontrunner and a depleted bench less than two weeks before voters head to the polls.

The stakes are straightforward: Wisconsin is a perennial presidential battleground, and the Democrat who survives this primary will face Trump-backed Republican Congressman Tom Tiffany in November. What's left of the Democratic field doesn't look like it can win it.

Barnes announced his exit in a video posted to X, saying he'd had a "very difficult conversation with staff" and that "it's become very clear who our nominee is going to be." That nominee is state Representative Francesca Hong, a democratic socialist who has opened a commanding lead. A Marquette Law School poll released Wednesday showed Hong at 38% support among Democratic primary voters, with Barnes at a distant 16%, Milwaukee County Executive David Crowley at 7%, and about a third of voters still undecided.

Barnes's departure comes with timing worth noting. The Milwaukee Journal Sentinel reported it had sent Barnes questions about anonymous allegations that he used his party position to pursue inappropriate relationships with "young adult women." The Wisconsin Democratic Party hired a law firm in 2025 to investigate the claims, but the review found no actionable evidence because the allegations were "anonymous and unspecific," according to the Journal Sentinel. Barnes's campaign denied any wrongdoing: "There are no allegations of misconduct or wrongdoing against Mandela."

Barnes is the third Democrat to exit the race. Lieutenant Governor Sara Rodriguez dropped out two weeks ago amid a campaign finance scandal over major inaccuracies in her financial reporting. Former state economic development director Missy Hughes ended her campaign earlier this summer. Crowley re-entered the race with outgoing Governor Tony Evers's endorsement — but NBC News revealed the existence of a years-old social media account registered to Crowley featuring incendiary posts about women, race, and what NBC described as "derogatory LGBTQ references."

So the moderate alternatives have collapsed, and the establishment's fallback candidate carries his own baggage. Some Democrats fear Hong's progressive views make her a weak general election candidate in a swing state. The Marquette poll found Barnes had been the only top Democrat leading Tiffany in a hypothetical general election matchup. That option is now gone.

Crowley moved quickly to court Barnes's supporters, writing on X: "To everyone who backed Mandela: there's a place for you in what we're building." A Crowley supporter described the coming blitz with Evers as a "Hail Mary" — acknowledging the endorsement may have come too late.

Meanwhile, a Wisconsin judge on Wednesday rejected a Democratic Party-backed effort to let absentee voters void their initial ballots and vote again, over concerns that many early votes had been cast for candidates no longer in the race.

Barnes was once the party's future — the first Black lieutenant governor in Wisconsin history who lost his 2022 Senate bid to Ron Johnson by fewer than 27,000 votes even as Evers won re-election. Now he's out, and the question is whether Wisconsin Democrats have anyone left who can compete where it counts.
