Berkeley surveyed 2,272 Californians likely to vote in the Democratic primary Sept. 13-18. Respondents were reached by email using the state’s official voter registration rolls, and the poll was conducted online.

California, the largest state in the nation, holds its vote on Super Tuesday — March 3 — of next year's primary, but voters can begin casting absentee ballots a full month earlier, the same day as the Iowa caucuses.

A survey conducted by Emerson earlier this month found Biden and Sanders tied for first at 26 percent in California, 6 percentage points ahead of Warren.

Wednesday's poll is the latest in a string of positive results for Warren, who also edged past Biden in a recent national poll from Quinnipiac University.
