Understanding Americans’ stance on Roe v. Wade is not as simple as looking at their opinion on abortion. Americans who call themselves “somewhat pro-life” subvert the idea that supporting access to abortion is simply polarized along pro-life and pro-choice lines. For Americans who consider themselves “somewhat pro-life,” a little more than one-third (37%) want Roe upheld and about one-third (33%) want it overturned. Three in ten (30%) are uncertain of their opinion.

But a majority of Americans who call themselves “strongly pro-choice” or “somewhat pro-choice” are certain that they do not want Roe v. Wade reversed. Similarly, a majority of those who call themselves “strongly pro-life” are certain that they do want it overturned.

One key trait distinguishes these somewhat pro-lifers from strong pro-lifers: somewhat pro-lifers are less likely to be religious than the strongly pro-life. A majority of those who are strongly pro-life (59%) say they practice a religion, compared to almost half that number (32%) for somewhat pro-lifers. About a quarter (25%) of somewhat pro-lifers say they do not belong to a religion, compared to 15 percent of strongly pro-life people.
