Poll: Biden slips but maintains lead over field

Former Vice President Joe Biden holds his advantage over the Democratic primary field but his lead has slipped, according to a poll released Wednesday.

The CNN poll conducted by SSRS found Biden had the support of 24 percent of Democrats and Democrat-leaning independents, a 5 point drop from the same survey in August.

{mosads}Sens. Elizabeth Warren (D-Mass.), at 18 percent, and Bernie Sanders (I-Vt.), at 17 percent, were the only two other White House hopefuls to poll in double digits.

Warren’s support grew 4 points since last month’s poll, while Sanders’s grew 2 points. While Sanders’s support has remained relatively steady since May, Warren has moved up 11 points in CNN surveys since then.

Sen. Kamala Harris (D-Calif.) registered 8 percent support, South Bend, Ind., Mayor Pete Buttigieg (D) received 6 percent and former Rep. Beto O’Rourke (D-Texas) polled at 5 percent.

No other candidates cleared 2 percent support. 

The survey’s results line up with the majority of primary polls which have found Biden, Warren and Sanders as the the front-runners for the nomination.

All three will feature on the same debate stage on Thursday.

SSRS surveyed 908 Democrats and Democrat leaning independents who are registered to vote between Sept. 5 and 9 by cellphone and landline. The margin of error for the sample is 4.3 points.
