The survey of 1,577 U.S. adults, which was conducted from May 3 to May 6, found that registered voters initially preferred a generic Democrat (44%) over a generic Republican (39%) by 5 percentage points when asked how they would vote in their district if the congressional election were being held today.

But when voters were asked to choose instead between a “pro-choice Democrat” and a “pro-life Republican,” GOP support fell to 31% while Democratic support held steady — more than doubling the gap between the two candidates, to 13 percentage points.

By the same token, 69% of Americans say they would “oppose Congress passing a law that bans abortion nationwide.” The Washington Post reported this week that conservative groups have already met with their congressional allies about a possible “nationwide ban on the procedure if Republicans retake power in Washington,” and several GOP senators have started sketching out policy details.
