Do you believe Bernie is going to steal this election from Hillary? Could we actually see her lose this? See how close Bernie is to taking this whole state from her.
The poll, released Wednesday night by the Public Policy Institute of California, showed Mrs. Clinton leading Mr. Sanders among likely voters, 46 percent to 44 percent — within the margin of error. A survey by the organization in March found Mrs. Clinton with a lead of 48 percent to 41 percent over Mr. Sanders.
The survey came as both Mr. Sanders and Mrs. Clinton have stepped up their campaign appearances here in anticipation of the June 7 primary. Mr. Sanders, after initially saying he would not advertise on television here — California is one of the most expensive states for television advertising, given its size and the number of media markets — took to the airwaves this week.
And Mrs. Clinton has quickly responded, with ads set to begin running on Friday in the Los Angeles, Fresno and Sacramento markets: one narrated by the actor Morgan Freeman, another highlighting Mrs. Clinton’s endorsement by the civil rights activist Dolores Huerta. The Clinton campaign will also run Spanish-language ads aimed at Latino voters, and translated commercials in Cantonese, Mandarin, Vietnamese and Korean.
For Mrs. Clinton in particular, the ad buy is a significant reversal: Her campaign had halted its advertising after her decisive victories in the mid-Atlantic states on April 26, aside from a brief return to television in Kentucky.
