The Democratic presidential contest in California remains extremely fluid — but not enough, at least so far, to provide an opening for Michael Bloomberg, who entered the race two weeks ago and was banking on winning big in the delegate-rich state, a new poll for the Los Angeles Times has found.

The survey by the UC Berkeley Institute of Governmental Studies found that both Sen. Elizabeth Warren of Massachusetts — the commanding front-runner in a September California poll — and former Vice President Joe Biden have lost ground among the state’s likely Democratic primary voters over the last two months.
