Filing for June Election Begins Today
In Los Angeles County, the ballot will include races for District Attorney and three seats on the Board of Supervisors, including Don Knabe's.

The filing period begins today for the June primary election, the first under the "top two" system.
Under terms of Proposition 14, approved by voters in the June 2010 primary, all candidates running for congressional, legislative and state constitutional offices, regardless of party, will appear on a single ballot.
The top two finishers will advance to the November general election.
