Former Vice President Joe Biden’s still the leader among the 2020 Democratic presidential hopefuls following last week’s debates, although he’s lost notable ground among voters in his own party. Bernie Sanders, the clear number two in previous surveys, now runs even with Senators Kamala Harris and Elizabeth Warren.

The latest Rasmussen Reports national telephone and online survey finds Biden with 30% support among Likely Democratic Voters, but that’s down from 39% at the end of May. Bunched in distant second are Sanders, Harris and Warren, all with 13% support, closely followed by South Bend, Indiana Mayor Pete Buttigieg with 11% of the Democratic vote.

In the May survey, Sanders was in second place with 19% support among his fellow Democrats, followed by Harris (12%), Warren (9%) and Buttigieg (6%).

Rounding out the latest survey - taken Sunday night - are New Jersey Senator Cory Booker with six percent (6%) Democratic support and Julian Castro, a former mayor of San Antonio and member of President Obama’s Cabinet, who earns three percent (3%) of the vote. Five percent (5%) prefer some other candidate, while seven percent (7%) of Democrats are undecided. (To see survey question wording, click here.)
