In a low-profile electoral upset that defied the difficult national political environment facing the GOP, a Republican candidate declared victory this week in a down-ballot race for a seat on the Prince William Board of County Supervisors in Virginia — for the first time in nearly 40 years.

But while Republicans are now rejoicing over their narrow win, it otherwise largely demonstrated how Democratic leaders effectively sacrificed the seat to the GOP rather than elevate an extremist member of their own party who had claimed the nomination.

The result underscored the extent to which local Democrats had swiftly mobilized to oppose their own nominee, Muhammed Casim, who faced backlash over a series of recently uncovered past social media comments in which he used racist, misogynistic and antisemitic language. The posts, written more than a decade ago, used the n-word as well as demeaning rhetoric targeting women. He also accused Israel of genocide and promoted a conspiratorial post about U.S. financial assistance to the Jewish state, among other extreme comments.

More broadly, the outcome is an atypical example of how the Democratic Party worked to meaningfully confront extremism within its own ranks, even if its efforts came at the expense of an easily winnable local seat that instead flipped to Republicans for the first time in decades.

Casim apologized for his comments but refused bipartisan calls to drop out of the race, which had motivated a Democratic challenger to launch a write-in campaign that ultimately helped siphon votes away from his embattled bid. He lost to Republican Jeannie LaCroix by a margin of 258 votes. Write-in candidates pulled in 744 votes — a relatively sizable total that appeared to have made a difference in the closely contested race.

“Opposing antisemitism, racism or misogyny isn’t a partisan position,” Marc Broklawski, a Jewish vice chair of the Virginia Democratic Party, told Jewish Insider on Wednesday. “It’s a floor, not a ceiling, and the least we should expect from any party, official candidate or voter. When Democrats hold that floor even when it’s costly, that’s something to be proud of. When we don’t, voters notice that too.” Casim’s campaign did not respond to a request for comment on Wednesday.

Though some prominent Democrats have sought to reject radicalism in their party, many Jewish party activists have begun to express a growing sense of unease about whether their longtime political home will remain welcoming, amid rising hostility toward Israel that has frequently crossed into antisemitism while producing alliances with controversial figures.

This week, for instance, leading Jewish groups spoke out against New York City Mayor Zohran Mamdani’s decision to host Mahmoud Khalil, the campus anti-Israel activist facing deportation who had justified Hamas’ terror attacks, for dinner at his official residence, while Democratic officials largely stayed silent.

Likewise, a mounting number of Senate Democrats have endorsed Graham Platner in his insurgent bid for Senate in Maine, brushing aside concerns about a recently covered Nazi tattoo whose provenance he has struggled to explain as well as associations with antisemitic conspiracy theorists that have continued to raise alarms among many Jewish party members.

And in Virginia, Jewish Democrats have denounced an anti-Israel state legislator, Sam Rasoul, who has called Zionism “evil” and a “supremacist ideology,” even as high-ranking state party officials have been reluctant to weigh in on his incendiary commentary.

By contrast, several Jewish activists and party strategists said they were encouraged that most Democratic leaders had enforced red lines in the Virginia supervisor election. Even if the party had been forced to endure a short-term hit in losing the seat, they suggested, it was healthy to set standards — particularly in a time of rising extremism on both sides of the aisle.

“Virginia Democratic leaders were clearly repulsed by Muhammed Casim’s racist, misogynistic and antisemitic social media posts,” Sara Forman, a Jewish party strategist who previously worked in the state, told JI. “Their actions, including calling Casim out publicly, should send a strong signal nationally that the entirety of the Democratic Party has not capitulated to the leftist narrative entirely.”

Such opposition was not unanimous, however, as the local party accepted Casim’s apology and said it would stand behind his campaign. “There’s a lesson in there about the integrity of voters and the lack of integrity — and therefore weakened legacy — among some Dem leaders,” Shannon Watts, a gun control activist who has also criticized Platner, wrote in an X post on Wednesday.

“Leadership means speaking out clearly and consistently against antisemitism, racism, misogyny, and not only when it is easy, but especially when it is not — and from whomever,” Eileen Filler-Corn, a Jewish Democrat and former speaker of Virginia’s House of Delegates, told JI. “These values should unite us. We can disagree on policy and politics, but standing against hate and discrimination in all forms should never be up for debate. Our credibility with voters depends on our willingness to apply that standard fairly and without hesitation.”

Still, with most Democratic elected officials in the county refusing to support Casim after his posts had surfaced near the end of the race, nonpartisan Jewish leaders and members of both parties voiced satisfaction regarding the strong show of resistance.

“We think it is imperative that both parties call out the fringe and hateful elements in their own parties, so we’re certainly glad to see the Democratic Party do it in this instance — especially when it was hard and cost them a seat,” Vicki Fishman, the director of Virginia government and community relations at the Jewish Community Relations Council of Greater Washington, told JI. “It’s an important lesson for everybody that hate is hate, and when you see the ugly rhetoric in your own house for what it is, it’s important to call it out.”

Gary Katz, a Jewish Republican activist in nearby Loudoun County, said he was “encouraged by the outcome” of Tuesday’s race, “where principled voices within the Democratic Party chose to reject a nominee whose past comments reflected racism, misogyny and antisemitism — even at the risk of losing the seat to a Republican.” He said the dynamic “mirrors efforts we’ve seen in the GOP, such as in Fairfax County, to keep hateful elements from gaining leadership roles,” referring to a recent election where Republicans beat back an extreme candidate for county chair who had spread antisemitic conspiracy theories.

“It’s a reminder that combating the rising scourge of antisemitism requires people of good conscience in both parties to prioritize our shared values over partisan wins,” Katz told JI on Wednesday. “We need more of this vigilance to ensure that extreme fringes on either side never hold power, and that we support responsible leadership, even when we disagree politically, rather than those who align with us but betray our core principles.”
