With 1st District Alameda County Supervisor Scott Haggerty announcing his retirement in 2020 after 24 years’ service, four hopefuls have announced they intend to run for the seat in the March 3, 2020 primary election.

If no candidate receives more than 50% of the total vote, the top two contenders would compete in the Nov. 3, 2020 general election. The filing period opens Nov. 11 and closes Dec. 6.

Dublin Mayor David Haubert and Vice-mayor Melissa Hernandez have both announced their candidacies, as have State Senator Bob Wieckowski, of Fremont and Fremont City Councilman Vinnie Bacon. Hernandez, Wieckowski and Bacon are Democrats; Haubert is an independent.


Bacon has served in one of the two at-large seats on the Fremont City Council since 2012.

Bacon has a degree in biology and graduate degrees in city planning and transportation engineering. He has been employed as an environmental engineer and a technical support manager at several companies.

He posted several position papers on his web site. On Valley Link, he voiced support for it, and noted the two worst bottlenecks are in eastern Alameda County — the Altamont on I-580 and the Sunol Grade on I-680.

In the long run, better land use planning is needed to remedy transportation problems, he notes. But the problem won’t go away. It’s important to ensure that southern Alameda County gets its fair share of funding for solving these transportation problems, Bacon said.

Bacon stated that he has never accepted campaign contributions from developers, publicly traded corporations, or special interests, and would continue to follow that policy, because “I want my constituents to know that without a doubt I have no conflicts of interest.”

Bacon has no current endorsements listed on his web page. His endorsers for re-election in 2016 were Wieckowski, Assemblyman Bill Quirk, the Sierra Club, California League of Conservation Voters, Alameda County Building Trades Council, and Fremont Unified School District Teachers Association.


Haubert said he is going all out to become supervisor, and will not run again for mayor, should he fail in the supervisor race. “It’s time to pass the torch,” he said. He joined the council in 2012, after 10 years on the Dublin Unified School District board. He served two years as a councilman, then won the mayor’s race in 2014, 2016 and 2018.

Haubert said he is not seeking reelection as mayor. Dublin has accomplished good things on his watch, he said. These include improving city parks, eliminating unfunded pension liabilities, balancing the budget and building strong reserves.

He’s been endorsed by former Assemblywoman Catharine Baker, Livermore Mayor John Marchand, Pleasanton Mayor Jerry Thorne, Danville Mayor Robert Storer, and San Ramon Mayor Bill Clarkson.


Hernandez is the fifth of seven children born to migrant farm workers in Dixon. Her online biography says that “the helping hand of a compassionate neighbor lifted her family into the middle class.” From that moment on, Hernandez dedicated her life to public service, and giving back.

Her focus on bringing more people into the middle class is reflected in the union endorsements she has received, Hernandez said. They include the Livermore police officers union, the Livermore-Pleasanton Fire Department local of the firefighters union, and the Laborers Union Local 304.

She became involved in the community when she began raising her children in Dublin nearly 20 years ago. She volunteered at her children’s school, served on the Little League board, became a Rotarian, and chaired the Dublin Human Services Commission.

Since being elected to the City Council in 2018, Hernandez has been active in representing Dublin on the Valley Link board, Livermore Amador Valley

Transit Authority, County Solid Waste Management Board, and the East Bay Community energy board.

Hernandez is the only woman announced as a 1st District candidate. She has the endorsement of Supervisor Wilma Chan, who represents the 3rd District, which includes Alameda, part of Oakland and San Leandro.

Chan is the only woman on the board, which has had few women serving in the past. “Alameda is a large and extremely diverse county,” Chan said in a statement. “Melissa not only brings an incredible perspective to the board with her background as the child of migrant farm workers, she brings proven results as a thoughtful policy maker and consensus builder.”


Wieckowski represents the 10th Senate District, which includes Fremont, Hayward, and portions of other cities. A Democrat, he defeated his Republican opponent by getting 75% of the general election vote.

He has chaired the Senate’s Environmental Quality Committee, where he worked on bills to deal with greenhouse gas reductions. Wieckowski says on his website that he has a 100% scorecard from the California Labor Federation and the League of Conservation Voters.

Wieckowski’s entry into the supervisor’s race comes after a bit of musical chairs involving Rep. Eric Swalwell’s erstwhile presidential bid. Earlier this year Swalwell announced that he would not seek reelection if he were to drop out of the crowded field of Democrats seeking to become the party’s presidential candidate. Wieckowski announced he would run for Swalwell’s congressional seat.

But after Swalwell changed his mind on seeking reelection, Wieckowski switched to the supervisor race.

Nearly two dozen state senators have endorsed Wieckowski, including Scott Wiener of San Francisco, who has introduced a package of bills to build more housing in the state, which Wieckowski has supported. Wieckowski also wrote a bill that enables homeowners to construct a secondary dwelling unit in their back yards.
