Harris and Warren rise and Biden slides after first Democratic debates

New CNN Politics Poll Conducted by SSRS

WASHINGTON (CNN)Sens. Kamala Harris and Elizabeth Warren have made steep gains after the first Democratic presidential debate, a new CNN poll conducted by SSRS, shows, with former Vice President Joe Biden’s lead over the field shrinking to a narrow 5 points.

The results indicate a significant tightening in the race for the Democratic nomination.

The poll, conducted after the two-night debate, finds 22% of registered voters who are Democrats or Democratic-leaning independents backing Biden for the party’s presidential nomination, 17% Harris, 15% Warren and 14% Sen. Bernie Sanders. No one else in the 23-person field tested hits 5%.

That represents a 10-point decline in support for Biden since the last CNN poll in May, while Harris, of California, has posted a 9-point increase, and Warren, of Massachusetts, has boosted her support by 8 points. No other candidates have seen significant movement since the last poll.

Harris’ numbers follow a strong showing on the second night of the debates. Among those who watched or followed news coverage about them, 41% say Harris did the best job in the debates, well ahead of the 13% who say Warren had the best performance and 10% who said Biden did.

Among those who say they watched all or most of at least one night of debates, Harris’ showing is even stronger: 46% say she did the best job, 19% Warren, 8% Biden and 5% each named South Bend, Indiana, Mayor Pete Buttigieg and former secretary of Housing and Urban Development Julian Castro.
