Quinnipiac noted that this is the first time a candidate other than Biden led in its 2020 polls since the university began them in March.

"After trailing Biden by double digits since March in the race for the Democratic nomination, Warren catches Biden," Quinnipiac University polling analyst Tim Malloy said in the statement. "We now have a race with two candidates at the top of the field, and they're leaving the rest of the pack behind."

Researchers surveyed 561 Democratic voters and independent voters who lean Democratic Sept. 19-23. The results have a margin of error of 4.9 percentage points.

Warren's campaign has seen significant momentum in recent months. Over the past few days, she has led Biden in a few polls while trailing him in others.

The two candidates are among more than a dozen who are vying for the 2020 Democratic presidential nomination.
