Well, no: abortions could be performed during the third trimester with restrictions if states chose to put restrictions in place.
Those laws were never intrusive, and were never intended to be. They were closer to superfluous. The rarity of medically optional third term abortions made it so.
The whole playing filed is fucked up now; Justices Thomas' and Alito's noses are under the tent, and good religious people are about to let the whole corrupt herd of camels into your doctor's office, your house, your kids' schools - the whole ball of wax.
