Sen. Bernie Sanders has widened his lead in California’s presidential primary just before the state is set to start sending out ballots to millions of voters, a new poll released Tuesday found, mirroring a trend of the Vermont senator’s momentum across the country.

The poll, conducted by UC Berkeley’s Institute of Governmental Studies for the Los Angeles Times, found Sanders in first place in the Golden State with 26 percent support among likely Democratic primary voters. He was followed by Sen. Elizabeth Warren of Massachusetts with 20 percent and former Vice President Joe Biden with 15 percent.
