A majority of voters think Roe v. Wade — the ruling that established a constitutional right to abortion — should remain intact, according to a new poll.

The Fox News poll released Wednesday found that 57 percent of voters said the landmark Supreme Court decision should remain intact. Another 21 percent of voters said the ruling should be overturned, while 22 percent said they were unsure. 

Among voters who are familiar with the case, 68 percent said the ruling should stand, 26 percent should it be overturned and 6 percent were unsure.

The poll also found that 73 percent of Democrats believe the ruling should be left alone, as do 43 percent of Republicans. Thirty-seven percent of Republicans think the ruling should be overturned, according to the poll.

The poll shows a closer split among voters in their views on abortion. The poll found that 44 percent of voters identify as anti-abortion, while 46 percent identify as pro-choice. 

The poll's results were based on interviews with 1,004 randomly selected voters from Feb. 10 through Feb. 12. The poll has a margin of error of plus or minus three percentage points.
