August 26, 2011 (LifeSiteNews.com) - While the number of U.S. voters calling themselves pro-choice maintains a slight edge over those calling themselves pro-life, most U.S. voters still say that abortion is morally wrong, according to a Rasmussen Reports survey.

The survey, released Friday, supports a long-term trend in feelings about the moral acceptability of abortion, as well as the dividedness of voters on “pro-choice” and “pro-life” labeling.

Fifty-five percent of participants in the survey said abortion was morally wrong in most cases, while 30 percent called it mostly acceptable, with 15 percent unsure. The pollster notes that the numbers are little changed since April 2007.

Among those surveyed 48 percent considered themselves pro-choice, while 43 percent called themselves pro-life.

In 2009, the “pro-life” label broke into the lead for the first time according to Gallup, which has asked the question since the mid-1990s, topping “pro-choice” among American adults 51 percent to 42 percent. It remained in the plurality until this year, when it slipped behind by four points.

Gallup’s abortion survey has also consistently found more Americans, usually over half of respondents, calling abortion morally wrong in general than morally acceptable.
