Biden lead shrinks, Sanders and Warren close gap: poll

Former Vice President Joe Biden still leads the Democratic presidential primary field in a Fox News poll released Wednesday, but Sen. Bernie Sanders (I-Vt.) and Sen. Elizabeth Warren (D-Mass.) are closing the gap. 

Biden’s 29 percent support from Democratic primary voters is down 6 percentage points from his highest poll numbers in May. The former vice president leads all other candidates by 11 points, compared to his 19-point lead in June.

{mosads}Sanders earned 18 percent support, the highest he has received in a Fox News poll. Warren dropped 4 percentage points from August to 16 percent support. 

Fifty-six percent of Democratic primary voters said they prioritize a candidate who has the best chance to beat President Trump, up 15 percentage points from March. Voters have traditionally seen Biden as the most electable, although the other candidates are closing the gap.

The former vice president and two New England senators are solidifying their status as front-runners in the race. 

Behind them are Sen. Kamala Harris (D-Calif.) at 7 percent, South Bend, Ind., Mayor Pete Buttigieg at 5 percent, former Rep. Beto O’Rourke (D-Texas) at 4 percent and Sen. Cory Booker (D-N.J.) at 3 percent.

Entrepreneur Andrew Yang and Sen. Amy Klobuchar (D-Minn.) follow at 2 percent.

Biden keeps the lead when distinguishing between white and nonwhite voters. But he has a 13 percentage point lead among nonwhite voters, compared to a 7 percentage point lead among white voters, which aligns with previous polls.

The poll was conducted between Sept. 15 and Sept. 17 with 1,008 registered voters. The margin of error is 4.5 percentage points for Democratic primary voters.
