Harris was the top choice of Black voters that support Biden, although half of them chose someone else, and one in four had no preference. In the West, her home region, a third of all Biden voters picked her (Massachusetts Senator Elizabeth Warren and Illinois Senator Tammy Duckworth were tied for second in that region).
But nationally, Harris has slightly more registered voters viewing her unfavorably as favorably (the same was true of Warren and many of the other candidates). Within the group currently committed to Biden, one in five say they view Harris unfavorably.
Black voters supporting Biden look the same as all Biden supporters in their opinion of Harris.
