The Democrats’ four-point edge represents a superficial advantage with Republicans, given the poll’s 3.5-point margin of error. Still, the finding marks a sharp turn from 2016, when voters in these districts backed Republicans by a margin of 15 percentage points.

Women continue to be key to Democratic hopes on Tuesday. White women with college degrees, a high-turnout group, currently favor Democratic House candidates by a 26-point margin, 62 percent to 36 percent.
