Massachusetts Sen. Elizabeth Warren has moved past Bernie Sanders and into 2nd place in the 2020 Democratic field. That's the finding of a Economist/YouGov national poll of likely Democratic primary voters. Warren's four point margin over the Vermont Senator reflects a 9 point change since last week.
It remains to be seen if this result is an outlier or the start of a trend. Sanders retains a lead of about 5% in the overall polling average. However, the 16% is Warren's high-water mark to date. She has made slow and steady gains since late April, when she first moved into double digits in a poll.
