Polling in the key state of California shows Sanders edging closer to the lead along likely Democratic primary voters.

The Field Poll released Wednesday morning put Hillary Clinton at 46 per cent and Bernie Sanders at 35 per cent, with a margin of error of 5.6 per cent. The poll shows his lead increasing in California by 5 points since an LA Times/USC released in September.

“Sanders leads Clinton among Democratic primary voters under age 40, and among independent voters who say they’ll be voting in the state’s Democratic presidential primary,” said Mark DiCamillo, Director of the Field Poll.

“When all registered voters statewide are asked their opinions of the two leading Democrats, each is viewed more positively than negatively, although slightly more voters statewide hold an unfavorable opinion of Clinton than Sanders.”

The poll put Martin O’Malley at one per cent in California.
