Bernie Sanders has won California’s Democratic presidential primary. The state has 415 delegates at stake, the biggest haul on the electoral map.

Sanders’ campaign has long seen the nation’s most populous state as a critical early contest and has had droves of volunteers organizing events across the state. Sanders lost the 2016 Democratic presidential primary to Hillary Clinton and was hoping for a comeback that would be a capstone moment for the state’s progressive wing.

Sanders has also won Utah, Vermont and Colorado. Joe Biden has won Massachusetts, Arkansas, Minnesota, Tennessee, Alabama, Oklahoma, North Carolina and Virginia.
