The Field Poll finds that Clinton leads by 9 points among registered Democrats, 49 to 40 percent, while Sanders leads among "non-partisan" voters, 54 to 27 percent.
Another NBC News/Wall Street Journal/Marist poll of likely Democratic primary voters in California released Wednesday night found Clinton similarly leading Sanders by 2 points, 49 to 47 percent.
