A supermajority of Americans supports significant restrictions on abortion, in contradiction to the Supreme Court decisions which require permissive laws nationwide, a new survey sponsored by the Knights of Columbus says.

“Almost four decades after the Supreme Court’s decisions in Roe v. Wade and Doe v. Bolton, which resulted in the almost totally unrestricted abortion regime of today, these decisions continue to be out of step with the vast majority of Americans,” said Carl Anderson, Supreme Knight of the Knights of Columbus.

The Knights of Columbus-Marist Poll survey found that 79 percent of Americans say they would not allow abortion after the first three months of pregnancy. Another 51 percent said they would only allow abortion, at most, in cases of rape, incest or to save the life of the mother or they would not allow it at all, the Knights reported Jan. 23.

Eighty-four percent of survey respondents said that laws can protect both the life of the unborn and the health and well-being of the mother, an increase of three percent since a survey two years ago.

“Far from being settled law, the inadequacy of the Court’s reasoning on abortion in Roe and Doe is readily apparent to most Americans. Once a survey moves beyond the labels of pro-life and pro-choice, we see a fundamental unity among Americans in favor of significant abortion restrictions,” Anderson said.

The survey questions on abortion were part of a broader survey that will be released in February. The survey polled 1,053 adults in the continental U.S. from Dec. 15 through Dec. 27, 2011. It claims a margin of error of plus or minus three percentage points.
