Amendment 14 federalized equal protection under law (which SCOTUS included privacy under 9 and 14 for abortion). The Civil Rights Act of 1875 gave the courts that power, under the provisions of Amendment 14's enforcement provisions. Any political science or law student who has had to read and be tested on Roe knows that. That after 4 decades this has not been explained to the pro-life movement shows it is an electoral scam, because the leadership surely must, unless they are all just that incompetent.
