A new poll shows Hillary Clinton's 2016 presidential bid has continued to gain momentum, giving her double the amount of support that Sen. Bernie Sanders, I-Vt., has received thus far.

The latest NBC News/Wall Street Journal poll shows the Democratic front-runner won over 62 percent of Democrats' support, while only 31 percent said they are backing the Vermont senator for their party's presidential nomination. Meanwhile, former Maryland Gov. Martin O'Malley received three percent of support.

Clinton's lead has gone up slightly from October when she scored 58 percent of voters compared to Sanders' 33 percent. The former secretary of state also regained her lead in some New Hampshire polls.

The new poll, which was conducted Oct. 25-29, also shows that over 80 percent of Democrats see themselves supporting Clinton for the nod, while only 61 percent say are backing the Vermont senator.

However, despite the increase in her lead over the other Democratic contenders, the survey also reveals that Clinton remains unpopular among the general electorate since only 40 percent said they had a positive view of her and 47 percent said they have a negative view. Plus, less than a third of the respondents gave the former first lady favorable marks for "being honest and straightforward." In addition, Clinton has failed to gain significant improvement with registered voters on issues like "being compassionate enough to understand average people" and "being inspirational and an exciting choice for president."

When asked to respond to Clinton's surge in the polls, Sanders told MSNBC's Andrea Mitchell on Tuesday that he is comfortable with being the underdog in the race.

"We are taking on the political establishment; we're taking on the economic establishment. We started as the underdog we are still the underdog. But the kind of enthusiasm that we are generating tells me that at the end of the day we are gonna win this election," he said, reports Politico.
