The District 1 seat on the Alameda County Board of Supervisors will advance to a two-person runoff election in November, but the candidate list for the fall is still too close to call after Election Night in the primary ballot.
The four candidates finished Election Night all within 1,255 votes of each other, but none reached anywhere near the 50%-plus of overall ballots that was required to win the seat outright in the primary election.
Dublin Mayor David Haubert sat in first place with 26.97% of the vote, according to unofficial results reported as of early Wednesday morning -- which represent the bulk, but not all, of the eligible ballots cast. District 1 covers Dublin and Livermore in the Tri-Valley, as well as Fremont and part of Sunol.
Fremont City Councilman Vinnie Bacon was in second place at 26.10% (233 votes behind Haubert), in position to advance to the runoff election in November if the order holds after remaining ballots are counted in the coming days.
Not far behind was Dublin City Councilwoman Melissa Hernandez, with 24.67%, trailing Bacon by 381 votes for second place.
Rounding out the list was State Sen. Bob Wieckowski, a Fremont resident who is terming out at the state level this year, with 22.26% of the vote.
The four candidates were vying to succeed Supervisor Scott Haggerty, who is retiring after six terms on the county board. Haggerty had given a dual endorsement ahead of the primary, supporting Hernandez and Wieckowski.
The unofficial election results include early vote-by-mail tallies and totals reported by the precincts on Election Night. The election figures will likely change in the coming days as final vote-by-mail ballots, provisional ballots and other qualifying ballots are processed, according to the California Secretary of State.
The Tri-Valley's other Board of Supervisors position, District 4 which includes Pleasanton, appears to be a done deal with incumbent Supervisor Nate Miley holding a nearly 2-to-1 lead after Election Night.
Miley garnered 67.20% of the vote in his bid for a sixth consecutive term, comfortably ahead of lone challenger Esther Goolsby, an environmental community organizer from Oakland, at 32.80%.
The clear majority over 50% would give Miley the victory outright in the primary election to retain his position representing District 4, which in addition to Pleasanton includes East Oakland, Montclair, Castro Valley, Ashland, Cherryland, Fairview and El Portal Ridge.
In the other Board of Supervisors race, which is outside of the Tri-Valley, District 5 Supervisor Keith Carson finished well ahead of lone challenger Albany City Councilman Nick Pilch -- 79.67% to 20.33%.
