Warren was just behind Harris, with her support climbing 1 point to 9 percent.

The polls are consistent with others showing Biden's lead slipped following the debate after Harris challenged Biden over his opposition to racial busing decades ago.

An ABC News/Washington Post poll also released Wednesday showed Biden leading the field with support from 29 percent of Democrats and Democratic-leaning independents. The poll showed 23 percent supporting Sanders, 11 percent supporting Harris and 11 percent supporting Warren. 

The ABC/Washington Post poll also found that Harris was seen as the standout performer in the first debate, with 41 percent saying so compared to 26 percent saying this of Warren, who was next highest of the four top-polling contenders. 

The ABC News/Washington Post poll of 1,008 adults, including 460 Democrats and Democratic-leaning independents, was conducted between June 28 and July 1 over the phone. Its results have a margin of error of plus or minus 5.5 points. 

The Reuters/Ipsos poll was conducted online and surveyed 2,221 adults, including 1,367 Democrats and independents. It had a credibility interval 3 percentage points. The previous Reuters poll conducted May 29 to June 5 with credibility interval of 2 percentage points.
