AP Photo Poll: Clinton opens 25-point lead over Sanders

Hillary Clinton surged to a 25-point lead over Bernie Sanders in the latest Bloomberg Politics national poll out Friday, as the former secretary of state continues to solidify her advantage among the Democratic base.

Clinton grabbed 55 percent, while Sanders took 30 percent. Former Maryland Gov. Martin O'Malley polled within the 5-point margin of error with 3 percent, while 8 percent said they were not sure and 4 percent said they were uncommitted.


Roughly six in 10 of the Democrats surveyed, however — 62 percent — said that they could still be persuaded on their choice for the nomination, while 37 percent said their mind is made up. Among Clinton supporters, 46 percent said they are set on their decision, while 54 percent said they could be persuaded. But among Sanders supporters, just 36 percent said they are decided and 64 percent could be persuaded in another direction.

Asked to answer a series of 15 questions about the candidate's qualities, those surveyed gave Clinton an advantage in 11, including on foreign policy, gun control and life experience. Voters preferred Sanders on issues related to reining in Wall Street, honesty and trustworthiness.

In the previous iteration of the survey conducted in September, Clinton picked up 33 percent to Sanders’ 24 percent, while Vice President Joe Biden, who has since ruled out a presidential run, earned 25 percent.

The poll was conducted Nov. 15-17 by Selzer & Co. of Des Moines, surveying 385 Democrats or Democratic leaners, with a margin of error of plus or minus 5 percentage points.
