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.
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.
