Many believed the race for the open Alameda County Board of Supervisors seat in the Tri-Valley and Fremont District 1 would be a wide-open affair. But early returns posted Tuesday night indicate the primary election may, in fact, be even more than of a toss-up than anybody could have predicted. The margin separating first to fourth is less than five points.

ALCOD1 logoDublin Mayor David Haubert leads the field of four with 26.61 percent of the vote, which represents early vote-by-mail ballots.

Fremont Councilmember Vinnie Bacon is second with 25.34 percent in a contest that is now almost certain to be a runoff in November between the top two finishers in tonight’s primary.

Dublin Councilmember Melissa Hernandez is currently third with 25.12 percent, just 33 votes behind Bacon for second.

And in a major surprise, if it holds, state Sen. Bob Wieckowski is in fourth place with 21.93 percent.
