From Pew:

Today, 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 Pew Research Center survey, conducted April 5 to 11, finds deep disagreement between – and within – the parties over abortion. In fact, the partisan divide on abortion is far wider than it was two decades ago.

White evangelical Protestants continue to be opposed to abortion in all or most cases. Around three-quarters of White evangelicals (77%) say it should be illegal in all or most cases, while 21% say it should be legal in at least most cases. In contrast, a majority of White Protestants who are not evangelical (63%) say abortion should be legal in all or most cases.

Religious “nones” – those who are religiously unaffiliated – overwhelmingly support legal abortion. Around eight-in-ten (82%) say it should be legal in all or most cases, while just 16% say it should be illegal.

Read it all. 

What goes unmentioned is Catholics. According to an accompanying graphic, 55% of Catholics surveyed say abortion should be legal in all or most cases.
