About half (53%) of the public says abortion is “not that important” compared with other issues, while 45% says abortion is either “one among many important issues” (27%) or “a critical issue facing the country” (18%), according to a recent Pew Research Center survey. But this split masks stark differences in opinion between those who say they attend religious services at least once a week (37% of U.S. adults) and those who say they attend less often. About two-thirds of weekly churchgoers say abortion is a critical or important issue, while roughly two-thirds of those who attend less often take the other view, that abortion is not that important an issue.
