Six red states have advanced bills to limit access to abortion, with Florida’s proposed 15-week ban the closest to passage.

Republican-majority states have been emboldened by signals that the Supreme Court will issue a ruling in June that essentially overturns the 1973 Roe v. Wade decision, which legalized abortion nationwide. The case, Dobbs v. Jackson Women’s Health Organization, poses the question of whether states can ban abortion before viability, the point at which survival is possible outside the womb — commonly estimated to be between 22 and 24 weeks of pregnancy. Justices held oral arguments in December, with the majority-conservative court signaling willingness to uphold the Mississippi law, possibly delivering a death blow to the precedent set by the Roe ruling.
