Kamala Harris has rocketed into the top tier of the Democratic presidential primary, while Joe Biden’s once double-digit lead has crumbled in a national poll taken after last week’s debate.
The CNN/SRSS poll, which was released on Monday and conducted entirely after the first two Democratic presidential primary debates last week, has Harris, the California senator in second place, among Democrats and Democratic-leaning independents who are registered to vote, at 17 percent.
Harris' surge places her firmly within the top tier, which now consists of four candidates. Biden still sits at the top of the pack with 22 percent, but his once-commanding lead has eroded significantly. Sen. Elizabeth Warren is in third with 15 percent, followed by Sen. Bernie Sanders’ 14 percent.
Both Harris and Warren saw sizable jumps in their support over a previous CNN national poll, taken at the end of May. Harris went up 9 points, from 8 percent in May, and Warren rose by 8 points, from 7 percent in May.
Biden is still the leader among black voters, 36 percent to 24 percent for Harris, but his advantage with what had been his strongest cohort is diminished.
