Hillary Clinton's performance at the first 2016 Democratic debate may be the cause of her now 20-point lead over Bernie Sanders

Hillary Clinton dominated at last week’s Democratic debate. And it seems that her straight-forward answers and no-nonsense demeanor has landed her a major lead over Bernie Sanders.

In the wake of the first 2016 Democratic debate, Clinton, 67, stands at 49 percent in the race for the Democratic nomination and Sanders, 74, lags behind with 29 percent – giving Clinton a 20-point lead, according to an NBC/Wall Street Journal poll. Other polls like CNN/ORC found Clinton’s percentage to be 45.

Joe Biden, who has not announced a presidential run and did not participate in last week’s debate, follows with a 15 percent backing, down from 17 percent last month, according to NBC News.

With Biden’s percentage out of the picture, Clinton’s lead jumps to 58 percent, and Sanders’s to 33.

According to the poll, no other Democratic candidate received more than two percent, NBC reports.

Clinton and Sanders, the two-top polling Democrats went head-to-head in the debate, arguing about hot-button issues like gun control. But the two seemed to agree about the email scandal that has plagued Clinton’s campaign for months.

“The American people are sick and tired of hearing about your damn emails!” Sanders declared at the debate.

The two dominated the event, prompting former Virginia Sen. Jim Webb to plead with debate moderator Anderson Cooper, “Can I get into this discussion?”
