Abortion has long been a contentious issue in the United States, and it is one that sharply divides Americans along partisan, ideological, and religious lines. According to a new Pew Research Center survey, a 59% majority of U.S. adults say abortion should be legal in all or most cases, while 39% think abortion should be illegal in all or most cases. These views are relatively unchanged in the past few years.

The latest survey finds deep disagreement between the parties over abortion. Democrats are 45 percentage points more likely than Republicans to say abortion should be legal in all or most cases. This gap is little changed over the last few years, but the current divide is wider than it was in the past.
