Most of the people talking about Roe v. Wade have. no idea what that decision said, or what has happened to "abortion law" in the interim.
The importance of RvW was that the Supreme Court MADE UP "CONSTITUTIONAL LAW" on its own. There was NOTHING in the Constitution on the subject, and all they had to go on was a couple thousand years of human history and a couple hundred years of common law and precedent, stating unequivocally that governments DO have the power to criminalize abortion - because they had been doing it all along.
Overturning RvW - depending on the actual case that is decided - will probably just send the issue back to the state legislatures, where each state could decide whether abortion is legal within its borders. Utah will outlaw it; Massachusetts and D.C. will offer a tax credit for abortion fees. The chances of the USSC stating unambiguously that "human life begins at conception" are slim and none.
CONSIDER: If the U.S. were as unanimous in support of abortion as Leftists claim we are, then it would be a simple matter to pass a Constitutional Amendment and take it out of the hands of the Courts.
But of course, there is no significant majority on either side of the issue.
And as for the question posed by the OP, criminalization of abortion would be as follows: The person performing the abortion (or facilitating the abortion in the case of drug-induced abortion) would be guilty of a felony, and the woman receiving the abortion would be guilty of a summary offense, and pay a fine. There would be the usual exceptions for "rape and incest," which are both bullshit, but most voters are not sophisticated enough to recognize that they are bullshit.
