The source of the shift in abortion views is clear in the Gallup Values and Beliefs survey. The percentage of Republicans (including independents who lean Republican) calling themselves “pro-life” rose by 10 points over the past year, from 60% to 70%, while there has been essentially no change in the views of Democrats and Democratic leaners…

A year ago, Gallup found more women calling themselves pro-choice than pro-life, by 50% to 43%, while men were more closely divided: 49% pro-choice, 46% pro-life. Now, because of heightened pro-life sentiment among both groups, women as well as men are more likely to be pro-life.

Men and women have been evenly divided on the issue in previous years; however, this is the first time in nine years of Gallup Values surveys that significantly more men and women are pro-life than pro-choice.
