Steve Glazer was sworn in as the Tri-Valley's new state senator in a ceremony this morning in Sacramento.
Glazer, an 11-year Orinda City Council member, won the seat by defeating Concord Assemblywoman Susan Bonilla, a fellow Democrat, in a special runoff election held last week.
The election margin stood at 54.5% for Glazer and 45.5% for Bonilla's, according to the semi-official results on the California Secretary of State website, which had not yet posted final official election totals as of Wednesday afternoon.
Voter participation was 26.24% of registered voters in State Senate District 7, which spans parts of Alameda and Contra Costa counties.
With the win, Glazer will complete the unexpired term of now-Congressman Mark DeSaulnier, who resigned from the California State Senate after being elected to the U.S. House of Representatives in November. The senatorial seat comes up for regular election next year.
Glazer's oath-of-office ceremony is set to take place at 9 a.m. on the State Senate floor at the State Capitol.
The 7th State Senate District includes Pleasanton, Livermore and Sunol at the south end, Brentwood, Antioch, Pittsburg and Concord to the north, Orinda, Lafayette and Walnut Creek to the west, and the San Ramon Valley.
