Former Secretary of State Hillary Clinton won the first Democratic presidential debate by a 23-point margin over Sen. Bernie Sanders (I-VT), according to an online poll for NBC News released on Friday.

The SurveyMonkey nationwide poll, which began as soon as the debate and ended Thursday morning, showed Clinton did the “best job” according to 56 percent of respondents while Sanders did the “best job” according to 33 percent. Former Maryland Gov. Martin O’Malley and former Rhode Island Gov. Lincoln Chafee earned a “best job” rating of 1 percent.

Former Sen. Jim Webb (VA) was the only debate participant to earn no rating.

In the poll, Clinton led the Democratic primary at 45 percent, followed by Sanders at 31 and Vice President Joe Biden at 10 percent. O’Malley and Webb both earned 1 percent.

The poll’s results came from 4,898 adults nationwide who were at least 18 years old. The margin of error was plus or minus 2 points. From the NBC News methodology: “Respondents for this non-probability survey were selected from the nearly three million people who take surveys on the SurveyMonkey platform each day.”
