(FOX40.COM) — With incumbent District 1 Supervisor Phil Serna opting to not seek reelection, the seat that represents a large part of Sacramento’s city core will be held by a newcomer for the first time in more than a decade.

Serna has held the position since 2010 and was re-elected three times. He announced his retirement in October 2025, endorsing Sacramento Mayor Pro Tem Eric Guerra as his successor. 

Guerra currently serves on the Sacramento City Council representing District 6 after first being elected to the role in 2015. He finds himself running against Dr. Flojaune Cofer, the epidemiologist and public health official who narrowly lost the mayoral race to Mayor Kevin McCarty in 2024.

The primary election in June saw Cofer win the largest share of the vote, with the 32,210 votes she received being good enough for 45.62% of all ballots. Guerra took home 20,760 votes of his own, accounting for 29.40% of votes cast.

Eric Guerra (D)

An immigrant from Mexico who grew up in Esparto, Eric Guerra has worked with the state Legislature for over 20 years. His campaign focuses on homelessness, human trafficking and housing, among other issues in the Sacramento area.

Guerra is endorsed by a long list of current and former elected officials, including but not limited to: former Sacramento Mayor Darrell Steinberg, the aforementioned Serna and U.S. Reps. Doris Matsui and Ami Bera. He’s also endorsed by organizations including the Sacramento County Deputy Sheriffs Association and the Sacramento County Young Democrats. 

More information on Guerra and his policies is available on his campaign website.

Dr. Flojaune Cofer (D) 

Flojaune “Flo” Cofer grew up in Pittsburgh, Pennsylvania, and obtained degrees from Spelman College in Atlanta, Georgia, and the University of Michigan’s School of Public Health before settling in Sacramento. She had been working in Northern California as an epidemiologist and public health official for over a decade when she decided to run for the position of Sacramento mayor in the 2024 election, losing by under 2,000 votes.

Her policies aim to protect marginalized groups, fight housing instability and create jobs for Sacramento County residents, alongside additional health and wellbeing based priorities. She is endorsed by organizations like the Democratic Party of Sacramento County, the Women Democrats of Sacramento County and the Sacramento Central Labor Council.
