Gov. Jerry Brown has scheduled the upcoming special election to fill the State Senate vacancy for the 7th District, which includes Pleasanton.
The primary election is set to occur on March 17, with the top two finishers to then square off in a special election on May 19, Brown announced Tuesday.
The State Senate seat was vacated by Mark DeSaulnier (D-Concord) after he was sworn in to the U.S. House of Representatives, having been elected to represent the 11th Congressional District in November. The term to be decided in the special election is set to expire in 2016.
Three candidates have thrown their hats into the race so far: Assemblywoman Susan Bonilla (D-Concord), former Assemblywoman Joan Buchanan (D-Alamo) and Republican attorney Mark Meuser.
In addition to Pleasanton, the 7th Senate District includes Brentwood, Antioch, Pittsburg and Concord to the north, Orinda, Lafayette and Walnut Creek to the west, Livermore to the south and the San Ramon Valley.
The Tri-Valley Democratic Club is set to hold a public candidate forum featuring Bonilla and Buchanan on Monday to help club officials decide who to endorse. The event is expected to begin at 8 p.m., following completion of the club's regular meeting, at the IBEW Local 595 Union Hall at 6250 Village Parkway in Dublin.
