Democrats are making Roe v. Wade a central theme in their opposition to Brett Kavanaugh’s nomination to the Supreme Court. And it might not be a bad strategy, if a recent poll is any indication.

According to a Wall Street Journal/NBC News survey, 71 percent of voters said they are opposed to overturning Roe, the landmark 1973 case protecting the right to an abortion. That’s a remarkable figure considering how polarizing abortion is in American political debate. Only 23 percent of voters said they want to see Roe overturned.

Support for Roe v. Wade is overwhelming among Democrats and independents: 88 percent and 76 percent, respectively. But even a majority of Republicans — 52 percent — don’t want to see the court ruling overturned.

That’s a gap that’s been widening since 1991, according to the Wall Street Journal. Margins are also opening up among voters who say they support pro-abortion rights candidates: 44 percent of voters, versus 26 percent who preferred anti-abortion candidates.

The WSJ/NBC News poll questioned 900 registered voters from July 15 to 18, with a margin of error of 3.27 percent.

This latest survey mirrors other polling that suggests the majority of Americans do not want to roll back abortion rights — even as Kavanaugh’s nomination to the Supreme Court makes it more likely than it has been in decades that Roe (and Casey v. Planned Parenthood, the 1992 decision that partly affirmed Roe) could be reversed or gutted. Justice Anthony Kennedy, whom Kavanaugh would replace, served as the conservative swing vote on the Court, but he often sided with the liberal wing when it came to social issues, including abortion access.

As Vox’s Dylan Matthews wrote, Kavanaugh’s presence on the Court could definitely put Roe at risk:

Kavanaugh will pretend this isn’t the case. Some conservatives — either to own the libs and prove that Kavanaugh isn’t a threat to women or to express concern about the choice — have cited his statement in his 2006 confirmation hearing that, “if confirmed to the D.C. Circuit, I would follow Roe v. Wade faithfully and fully.”

Matthews points out that this is clearly a dodge: As a DC Circuit Court judge, Kavanaugh has to honor the precedent of the Supreme Court. As a Supreme Court justice, not so much:

Kavanaugh, of course, will face lots of questions about his stances on these cases during his confirmation hearing — though he’ll likely refrain from answering, as is the growing tradition among Supreme Court nominees.

But so far, voters don’t seem completely sold on Trump’s SCOTUS pick. Just 32 percent of voters support Kavanaugh’s nomination to the bench, according to the poll. Slightly less — 26 percent — are opposed. Another 41 percent said they don’t have enough information yet about Kavanaugh, which means Republicans, Democrats, and Kavanaugh himself still have room to make their case to the American people.
