Poll: Hillary Clinton Hits 50 Percent Support

Allison Kopicki and John Lapinski

Hillary Clinton continues to dominate the now smaller Democratic field of candidates in the first NBC News online poll conducted by SurveyMonkey taken after Joe Biden officially declared himself out of the presidential race. With Jim Webb and Lincoln Chafee also suspending their campaigns, the poll shows that while Clinton has reinforced her lead to 20 points, Bernie Sanders remains a force to consider, with strong support from younger voters and those dissatisfied or angry with the government. 

With Biden no longer asked about, Clinton's numbers have inched higher, pushing her back to the 50 percent mark among voters who are Democratic or lean Democratic, for the first time since we began polling on the primary race back in April. But Sanders continues to hold onto a solid segment of the Democratic electorate, getting the backing of 30 percent leaned Democratic voters. Martin O'Malley and Larry Lessig, with just 1 percent support, have not been able to make a dent in their levels of support.

The tables below show that the last two weeks have been good ones for Hillary Clinton. Following the Biden announcement and her marathon 11 hour session before the House committee investigating the 2012 Benghazi attacks, Clinton is maintaining or building her coalition across a wide swath of voting blocs: Men, women, whites, blacks, and older voters.

But Bernie Sanders inspires younger voters and those that are angry with Washington — a key demographic in an election year where voters are embracing candidates who are considered outsiders. Among all Democratic leaned voters, less than 1 in 4 are satisfied (23%) or enthusiastic (1%) about how the federal government is working. A full 50% are dissatisfied and another 25% express anger. Among these angry voters, Sanders bests Clinton, 43% to 38%.
