In another Senate district, term limits are forcing out Sen. Sheila Kuehl (D-Santa Monica), setting up a Democratic contest featuring Assemblyman Lloyd Levine of Van Nuys and former Assemblywoman Fran Pavley of Agoura Hills.
Term limits prevent Sen. Bob Margett (R-Arcadia) from running for reelection in his district in the San Gabriel Valley. The Republican primary there features Assemblyman Bob Huff of Diamond Bar and former Assemblyman Dennis Mountjoy of Monrovia.
In the San Francisco area, Sen. Carole Migden (D-San Francisco) faces tough challenges from Assemblyman Mark Leno (D-San Francisco) and former Assemblyman Joe Nation, a Democrat from Sonoma.
In Orange County, former Senate Minority Leader Dick Ackerman (R-Irvine) cannot run for reelection in his mostly Republican district because of term limits. Contenders to replace him include Assemblywoman Mimi Walters of Laguna Beach and Anaheim City Councilman Harry Sidhu, both Republicans.
On the Assembly side, the contest to replace Levine in his heavily Democratic district includes Stuart Waldman, Levine's former chief of staff; Laurette Healey, a Democrat and a former advisor to the state controller; and Robert Blumenfield, district director for Rep. Howard L. Berman (D-Valley Village).
Some cities, counties and school districts will decide local ballot questions Tuesday.
City officials in Covina and Torrance want to extend existing utility taxes, while South Gate residents are being asked to approve a one-cent sales tax increase to help pay for basic city services.
In Riverside County, voters will determine whether Menifee, Quail Valley, Sun City and parts of Romoland should become their own city and, if so, whether it should be named Menifee or Menifee Valley.
