With polls showing Hillary Clinton and Bernie Sanders in a virtual tie before Tuesday's primary, both campaigns are pulling out the stops with final appeals to voters Monday in and around Los Angeles and the San Francisco Bay Area.
More than 2 million Californians have already returned their vote-by-mail ballots, but the two campaigns seem to be leaving no stone unturned while urging their supporters to vote.
Hillary Clinton has Monday events planned in Lynwood, Long Beach and Los Angeles. Bill Clinton has scheduled appearances in San Francisco, Oakland, Hayward, Richmond and Antioch.
Bernie Sanders is spending some of his last day before Tuesday's primary at an afternoon concert at Crissy Field in the Presidio in San Francisco. Among the musicians listed on the bill are Dave Matthews, Fishbone and Oakland's Fantastic Negrito.
At a stop in Sacramento on Sunday, Hillary Clinton implored thousands of supporters packed into a community college gym to cast their ballots.
