Biden’s lead continues to be based on strong support from African-Americans, from those 65 and older, and from Democratic voters in the Midwest and South. Biden, Warren and Vermont Senator Bernie Sanders are tightly bunched at the top in the Northeast and West. Only among liberals does Warren lead Biden, but Biden is far ahead among moderates, with Buttigieg tied with Warren with this group. Most Democratic voters have a choice: just 7% are unsure.

The other Democratic candidates currently are far behind. California Senator Kamala Harris, who just left the race, was in fifth place, but with only 4% support. Former New York City Mayor Michael Bloomberg, who just joined the race, New Jersey Senator Cory Booker, and Minnesota Senator Amy Klobuchar are next at 3%.
