For the primary ballot

CALIFORNIA VOTERS MAY NOT mind a little homework, but the assignments seem to get longer and more difficult every election. Tuesday's primary vote may actually be more of a final exam than the general election in November. The Democratic and Republican parties have drawn legislative districts so carefully that, in most races, the winners of the primary on Tuesday are all but assured of victory five months from now.

Recognizing that, we interviewed more than 70 candidates and made endorsements in 25 races, from governor to the state Board of Equalization, and on two ballot measures. We endorse selectively, on a case-by-case basis, with special attention to races for which voters have little candidate information, such as Superior Court judges.

We will make our decisions about many of the higher-profile races, in which both candidates stand a fighting chance, closer to Election Day in November. But where we have made a recommendation, we have chosen the person we believe to be the best candidate, even if we are less than enthusiastic about the entire field. That's how we felt about the Democrats' choices this year for governor. Also, like any voter, we reserve the right to pick an opposing candidate in five months, if there is in fact a viable opponent.

Here are our recommendations for the state primary election Tuesday. Complete editorials on each endorsement, and a handy clip 'n' save guide, can be found at www.latimes.com/endorsements.

STATE OFFICES

Governor: Phil Angelides. Both leading Democrats, state Treasurer Angelides and state Controller Steve Westly, have run uninspiring and negative campaigns, disappointing voters looking for a solid opponent to face Republican incumbent Arnold Schwarzenegger in November. But at least Angelides has been unwavering in his criticism of quick fixes and false budget promises.

Attorney general: Jerry Brown. Brown sports a remarkable career trajectory, from secretary of state and governor in the 1970s to presidential candidate and party boss, then radio gadfly and now mayor of Oakland. His record shows a rare combination of innovation and pragmatism. Los Angeles City Atty. Rocky Delgadillo has done some admirable things in his current job but cannot match Brown's breadth of experience.

Superintendent of public instruction: Jack O'Connell. O'Connell has proved a steady and prudent steward of the state Department of Education and deserves reelection to this nonpartisan post.
