How does the president overturn Roe V. Wade? Change the judges on the Supreme Court? And then you’d still need a relevant case to make its way to the SC which is entirely out of the hands of the President. Better to push for a Constitutional Amendment to protect life, prohibit cloning and fetal harvesting, and prohibit genetic discrimination in employment and insurance.
Not needed.
Just get your Congressman (and a majority of them) to remove the issue of abortion from the courts.
Let me know when your Congressman is willing to do that.
