Democratic presidential hopeful Elizabeth Warren has overtaken rival Joe Biden in four out of five recent polls, and that performance puts her at No. 1 in a widely followed average of surveys.

Warren, the Massachusetts senator, scores 26.6% support in a RealClearPolitics average of polls, just ahead of the former vice president’s 26.4%.

Her average has topped Biden’s after she achieved 29% support in a new Quinnipiac University poll and got 27% in a new IBD/TIPP poll, besting Biden’s 26% in both surveys. She also drew 26% support in an Economist/YouGov survey out last week, topping Biden’s 22%, and she got 28% in a Monmouth University poll vs. Biden’s 25%.

But Biden came out comfortably ahead in the latest Politico/Morning Consult poll, scoring 33% support vs. Warren’s 21%.

In the RealClearPolitics average of polls as of Tuesday, Warren and Biden stand well ahead of the rest of the field. Vermont Sen. Bernie Sanders scores 14.6% support, topping South Bend, Ind., Mayor Pete Buttigieg at 5.6%, California Sen. Kamala Harris at 4.4% and entrepreneur Andrew Yang at 2.8%. All other Democratic candidates hoping to challenge President Donald Trump in 2020 are at 2% or below.

Biden revealed last week that his campaign raised $15.2 million in the third quarter, behind Sanders’s field-leading Q3 total of $25.3 million, Warren’s $24.6 million and Buttigieg’s $19.1 million. The quarterly fundraising figures come as a dozen Democratic presidential candidates are due to face off in an Oct. 15 debate.
