Former Vice President Joe Biden remains the front-runner among the 2020 Democratic presidential hopefuls – despite not officially entering the race – and he performs the best of those potential nominees in a hypothetical matchup with President Donald Trump. That is according to a new poll out today released by Fox News. Biden performed the best of the potential Democratic nominees in a theoretical head-to-head matchup with Trump. If the election were held today, 47 percent of voters say they would vote for Biden, and 40 percent say they would vote for Trump. The poll found Bernie Sanders also winning a contest with Trump, although by a narrower 44 to 41 percent. The other two potential matchups against Trump that pollsters looked at were Senators Elizabeth Warren and Kamala Harris. Harris trailed Trump 39-41, and Warren was behind 40-42. We should note that this poll was conducted BEFORE the results of the Mueller probe were publicly announced.
