Overturning RvW would throw the issues back to the states. Currently, 15 states have criminal bans that would outlaw abortion throughout pregnancy: AL, AR, AZ, CO, DE, LA, MA, MI, MS, NM, OK, UT, VT, WI, WV. 27 states have bans that would outlaw abortion as early as 12 weeks, with no health exception: AK, AL, AR, AZ, FL, IA, ID, IL, IN, KY, LA, MI, MO, MS, ND, NE, NJ, OH, OK, RI, SC, SD, TN, UT, VA, WI, WV.
So, to answer your question: In 32 states (the 27 plus CO, DE, MA, NM, and VT) abortion would be illegal.
