Biden maintains double-digit national lead on Warren: poll

Former Vice President Joe Biden holds a double-digit lead over the rest of the Democratic presidential field, including his closest rival Sen. Elizabeth Warren (D-Mass.) ahead of Tuesday night’s Democratic debate, according to a poll.

The Morning Consult poll released Monday shows 32 percent of likely Democratic primary voters nationwide support Biden while 21 percent say they back Warren. 

{mosads}Sen. Bernie Sanders (I-Vt.) was the only other candidate in double digits, gaining support from 19 percent of primary voters. He was trailed by Sen. Kamala Harris (D-Calif.) with support from 6 percent of voters and South Bend, Ind., Mayor Pete Buttigieg (D) with 5 percent. 

Biden was down 1 percentage point from the previous week, while the other candidates’ support rates remained consistent. 

Researchers surveyed 15,683 people who indicate they may vote in the Democratic primary or caucus. The results have a margin of error of plus or minus 1 percentage point. 

Biden, Warren, Sanders, Harris and Buttigieg are among a dozen Democratic candidates who will face off in Tuesday night’s debate in Westerville, Ohio.
