As the 40th anniversary of the Roe v. Wade Supreme Court decision takes place on Tuesday, a majority of Americans – for the first time – believe abortion should be legal in all or most cases, according to a new NBC News/Wall Street Journal poll.

What’s more, seven in 10 respondents oppose Roe v. Wade from being overturned, which is the highest percentage on this question since 1989. …

By comparison, just 24 percent now want the Roe v. Wade decision overturned, including 21 percent who feel strongly about this position.

Much of this change, the NBC/WSJ pollsters say, is coming from African Americans, Latinos and women without college degrees — all of whom increasingly oppose the Supreme Court decision from being overturned.
