Biden had the support of 50 percent of non-white Democratic primary voters in the CNN/SRSS survey, by far the lion’s share of the demographic. Sen. Bernie Sanders (I-Vt.) trailed in second place with the support of 14 percent of non-white voters, while Sen. Elizabeth Warren (D-Mass.) earned 7 percent.

Among white Democrats, the race is closer. Biden holds the support of 29 percent of white Democrats, according to the poll, while Sanders had 15 percent.

Sen. Elizabeth Warren (D-Mass.), in third place overall in the poll, enjoys also about the same amount of support among white voters (8 percent) as she does among voters of color (7 percent).

And South Bend, Ind. Mayor Pete Buttigieg (D), in fourth place, enjoys the support of 10 percent of white Democrats for the primary, but registers just 3 percent support among voters of color.
