Voters in Elk Grove and south Sacramento are staring down a political déjà vu. Incumbent Assemblymember Stephanie Nguyen and Republican challenger Vinaya Singh are headed for a repeat showdown in California’s 10th Assembly District, with no other names on the June ballot and a near‑certain rematch in November. The race will test whether Nguyen’s record of bringing home state money and local projects can fend off Singh’s outsider pitch in a district that leans heavily Democratic.
Who’s on the ballot
The California Secretary of State’s certified candidate list shows that only Nguyen and Singh filed to run in the 10th Assembly District primary, which means both are guaranteed spots in the November general election, according to the California Secretary of State. The filing identifies Nguyen as the Democratic incumbent and Singh as the Republican challenger.
Where the district stretches
The 10th Assembly District blends Elk Grove suburbs with Sacramento neighborhoods, including Florin, Fruitridge, the Pocket and parts of south Sacramento, territory both campaigns repeatedly reference on the trail, per the Vinaya Singh campaign. That mix of suburban and city precincts helps explain why ground game, neighborhood endorsements and local visibility carry extra weight in this contest.
Money and voter math
The district has about 275,094 registered voters and is a solid Democratic stronghold: more than half of registrants are Democrats, while Republicans account for roughly one‑fifth, figures that shape both campaigns’ strategies, as reported by The Sacramento Bee. Nguyen’s campaign finance picture reflects that advantage; the outlet reports her committee spent more than $417,000 in 2025 and had about $360,922 in cash on hand as of early April 2026 after raising over $500,000 last year. Those funds have been used to keep field operations and voter outreach running across Elk Grove and south Sacramento.
Nguyen’s record
Nguyen is leaning hard on a message that she brings state dollars back home. Her campaign highlights work to secure state funding for local homelessness programs and community nonprofits, including a $5 million effort for regional homeless services, according to the Stephanie Nguyen campaign. Her campaign and office also point to investments in food banks and other nonprofits, and the district’s political establishment is visibly lined up behind her. Endorsements from allies such as Rep. Ami Bera, Elk Grove Mayor Bobbie Singh‑Allen and several labor and public‑safety groups are listed on the endorsements page of the Stephanie Nguyen campaign.
Singh’s pitch
Singh is running as an anti‑establishment alternative, arguing that he wants to limit outside influence by abolishing political action committees and saying he is not pursuing traditional fundraising and endorsements, per the Vinaya Singh campaign. A retired engineer who immigrated from rural India and later became a U.S. citizen, Singh previously challenged Nguyen in 2024 and captured roughly one‑third of the vote, according to public election returns. His platform centers on cracking down on sanctuary policies, giving local school boards more control over curriculum and prioritizing services for U.S. citizens.
What’s next
The June primary is scheduled for June 2, 2026, according to the California Secretary of State’s election calendar. Because only two candidates filed, this primary functions more like a dress rehearsal than an elimination round and sets up a straight‑line path to a November rematch, according to the Secretary of State. Voters in Elk Grove and south Sacramento can expect an uptick in mailers and digital ads as both sides pivot to a general‑election strategy, and turnout in those communities is likely to decide whether Nguyen maintains her Democratic edge or Singh tightens the gap.
