The race to replace Assemblyman Guy Houston, the Bay Area's only Republican elected official in a partisan seat, has already drawn candidates numbering in the double-digits.
The latest entry in the race is Joan Buchanan, who filed a statement of intention to run papers with the Secretary of State's Office last week.
Buchanan has served four terms as president of the San Ramon Unified School District.
She is a Democrat, and the eleventh candidate to line up in the race.
Never miss a local story.
The seat is expected to be one of the few hotly contested Assembly contests in 2008, along with the seats currently held by Assemblywomen Nicole Parra, D-Hanford, and Shirley Horton, R-San Diego.
All three lawmakers are termed out in 2008.
The Contra Costa Times' Lisa Vorderbrueggen has a rundown of the others in the contest in Houston's Assembly District 15.
The other Democrats are Danville airline pilot Steve Filson; Castro Valley businessman Fred Klaske; Elk Grove resident Davies Ononiwu; Livermore school principal Chris Van Schaack; and Danville electrician Stevan Thomas.
The Republicans have added another nominee to their ranks, as well, although the man is far less well known than Buchanan.
Joe Rubay, a partner in his family's Danville real estate appraisal company, an Alamo resident and a party activist, says he has formed an AD15 campaign committee.
The other GOP candidates are San Ramon optometrist Scott Kamana; retired auto dealership owner Robert Rao; Pleasanton businesswoman and party activist Judy Biviano Lloyd; and San Ramon Mayor Abram Wilson.
