Hillary Clinton is leading Vermont Sen. Bernie Sanders by a solid 25 points nationally, according to the latest Bloomberg Politics poll released Friday.

Among registered Democrats and those likely to lean towards the party, Clinton has garnered 55 percent of support, compared to Sanders' 30 percent. That's up from a September survey, which included Vice President Joe Biden, where Clinton held a nine-point advantage at 33 percent to Sanders' 24 percent.

The poll shows former Maryland Gov. Martin O'Malley at just 3 percent. Twelve percent of voters remain unsure or uncommitted to a candidate.

The survey also saw Clinton's favorability numbers rising: Forty-two percent of voters view Clinton as "very" or "mostly" favorable -- up from 38 percent in September.

Clinton's supporters also tend to be more loyal. Forty-six percent of her backers say they've made up their mind and can't be persuaded by another candidate, compared to 36 percent of Sanders's supporters.

The poll, conducted just days after the second Democratic primary debate and after multiple attacks terrorized Paris last week, showed Clinton also dominates over Sanders on issues like combating Islamic terrorism, possessing a better presidential temperament, and working most effectively with Congress. Clinton's trustworthy levels, however, still lag behind her Democratic rival: Thirty-six percent of respondents viewed her as the most honest and trustworthy, while 49 percent said the same of Sanders.

The survey was taken from November 15-17 among 1,002 adults, with 385 people identifying as registered or likely Democrats. The margin of error is 3.1 percentage points, with a margin of error of 5 percentage points for the Democratic sample.
