In a race between Sanders and Trump, 48 percent of survey respondents also said they would choose the Vermont senator over the president. Forty-one percent said they would vote for Trump, while three percent said they would vote for “other” if given the option.

Six percent said they are not sure who they would vote for between Sanders and Trump, and 2 percent said they would not vote.

However, when asked “Who do you think will win the 2020 presidential election?” 49 percent of survey respondents said the eventual Democratic nominee, while 51 percent predicted that Trump will win another term in office.

Biden currently leads Sanders in the Democratic primary, 1,186 delegates to Sanders’s 885. The former vice president made a direct appeal to Sanders's younger supporters earlier this week after sweeping victories in the Florida and Illinois primaries.

"Sen. Sanders and I may disagree on tactics, but we share a common vision for the need to provide affordable health care for all Americans, reduce income inequity that has risen so drastically, to tackling the existential threat of our time: climate change," Biden said in remarks via a livestream from his home state of Delaware.

"Sen. Sanders and his supporters have brought a remarkable passion and tenacity to all of these issues. Together, they have shifted the fundamental conversation in this country," he continued. "So let me say, especially to the young voters who have been inspired by Sen. Sanders: I hear you. I know what's at stake. I know what we have to do."
