If you are against abortion but not for punishing anyone it neutralizes the issue.
I know this will be unpopular to hear - and I am pro life - but the Republican party is hamstrung by the pro lifers. Many women would vote conservative if not for the pro abortion stance. To many women keeping abortion legal is like the 2nd amend is important to conservatives.
Even back in the sixties when a lot of states didn’t allow abortions they only went after the doctor not the woman. That’s why most doctors would not do it as they didn’t want to face the very stiff penalties that were in place back then.
