The Vermont senator, who has had strong support from Latinos and young voters, has been propelled into the top spot by voters who self-identify as “very liberal,” according to the latest UC Berkeley Institute for Governmental Studies poll, conducted for the Los Angeles Times.

Sanders has support from 26% of voters likely to cast ballots in the state’s March 3 Democratic primary, drawing support from liberals largely at the expense of Massachusetts Senator Elizabeth Warren. Warren is now backed by 20% of likely voters, which is down from earlier surveys showing she had 22% in November and 29% in September in the state.

The rest of California’s likely primary voters remain divided among several candidates, which has left the party’s front-runner nationally, Vice President Joe Biden, with only 15% in the most populous state.

That cut-off is important in California because, under the state Democratic Party rules, delegates are awarded only to those candidates with at least 15% of the vote statewide or in individual congressional districts. The remaining candidates in the poll are all below that, with former South Bend Mayor Pete Buttigieg at 7%, former New York Mayor Michael Bloomberg at 6%, Senator Amy Klobuchar of Minnesota at 5%, businessman Andrew Yang at 4% and billionaire Tom Steyer at 2%.
