The constitutionally protected right to abortion was struck down by the U.S. Supreme Court on Friday, leaving millions of women in the U.S. with less control over their own bodies than they had the day before — and for nearly 50 years before that.

Despite right-wing jubilation over the ruling, overturning Roe v. Wade may not be widely popular in the U.S.; recent polling by CNN suggests about two-thirds of Americans didn’t want it to happen. But there are so-called trigger laws on the books in at least 13 states that ban or severely limit abortion and come into effect virtually as soon as Roe v. Wade was overturned. Other states may also move to restrict or ban abortions soon.

Today on Front Burner, UC Davis legal historian Mary Ziegler — author of Dollars for Life: The Anti-Abortion Movement and the Fall of the Republican Establishment — discusses why the conservative-majority court overturned Roe v. Wade, why modern abortion bans have dangers not seen since the 1970s and what widespread criticism of the decision means for the perceived legitimacy of the court.
