Hilda Solis, the longtime Los Angeles County supervisor and state Democratic Party-endorsed candidate, enters the June 2 nonpartisan primary for the newly redrawn California 38th congressional district as the clear frontrunner among four candidates. The open seat, created after redistricting under Proposition 50, sits in a heavily Democratic area with a strong partisan voting index favoring Democrats. Fellow Democrats Monica Sanchez, a mayor pro tem, and Erik Lutz, a councilman, along with Republican Pedro Casas, round out the field. With the primary just days away, voter turnout among Democratic-leaning blocs in the Los Angeles area will determine which two candidates advance to the November general election under California’s top-two system. No major late-campaign developments have shifted positioning in recent weeks.
