Biden holds 28% support among Democrats and Democratic-leaning independents who are registered to vote, followed by Sanders at 17%, Warren at 14% and Buttigieg at 11%.

No other candidate reaches 4%, meaning the poll does not result in any changes to the lineup for the Democratic National Committee’s December debate. A cluster of four candidates stand at 3%, including the latest entrant to the race, former New York City Mayor Michael Bloomberg. He is joined by Sen. Kamala Harris of California and businessmen Tom Steyer and Andrew Yang. Sens. Amy Klobuchar of Minnesota and Cory Booker of New Jersey have 2% each in the poll.

The findings suggest slight declines in support for Biden and Warren since October, and a modest increase in backing for Buttigieg. Sanders’ support remains about the same as it was in October.
