Sen. Kamala Harris (D-Calif.) surged into second place following last week’s Democratic presidential debates, cutting deep into former Vice President Joe Biden’s long-held lead in the primary contest, according to a national poll released Tuesday.

Harris soared to 20 percent in the Quinnipiac University survey, while Biden fell to 22 percent among Democrats and Democratic-leaning voters.That’s a significant change from a Quinnipiac poll released last month that showed Biden leading the pack with 30 percent and Harris lingering in a distant fourth place with 7 percent support.

The Quinnipiac survey is the latest in recent days to show Harris riding a wave of new support following her standout performance in Thursday’s debate.

A CNN/SSRS poll released Monday showed the California senator jumping into second place with 17 percent support. Likewise, a Suffolk University Iowa poll found Harris surging into second in the crucial first-in-the-nation caucus state.
