Hillary Clinton is again topping the 50 percent mark among 2016 Democratic presidential voters in the wake of Vice President Joe Biden formally declaring that he will not be a candidate.

According to MSNBC, with Biden, former Virginia Sen. Jim Webb and former Rhode Island Gov. Lincoln Chafee all recently ending or suspending their candidacy Clinton has reestablished her 20 point lead over Vermont Sen. Bernie Sanders based on the latest figures tabulated by SurveyMoney.

The former Secretary of State and New York Senator now polls at 50 percent of the vote, compared to Sanders' 30 percent. Much of Clinton's widening margin has been gained over the last two weeks, a time that has witnessed Biden's announcement and Clinton's sparkling shown in a Republican-led marathon House committee session probing the Benghazi attacks of 2012.

The suddenly overwhelming coalition being built the former First Lady is said to include male, female, black, white and older voters. Her tabulations are the highest she has received since the campaign season poll has been conducted and represent a five point uptick since the last poll.

Meanwhile, the liberal-minded Sanders continues to attract the support of younger and more disenchanted voters, but the question has now become if it will be enough.

The poll shows among all Democratic leaned voters, less than 1 in 4 are satisfied (23 percent) or enthusiastic (1 percent) about how the federal government is working and a full 50 percent described themselves as dissatisfied, with 25 percent of those respondents billing themselves as feeling anger. Among the latter sector, Sanders leads Clinton 43 to 38 percent.

Conducted from Oct. 27-29, from among 8,706 would-be voters, the poll was produced by the Data Analytics Lab of NBC News in conjunction with Penn's Program on Opinion Research and Election Studies with data collection and tabulation conducted by SurveyMonkey.
