I understand that. But what I want to know is what a President can DO that would be tenable for you.
In actuality, all three branches, along with the people of this country, have the duty to demand equal protection for the millions of unborn children who are killed year after year. The president could refuse to enforce an unconstitutional order from the bench, could call upon Congress to impeach judges, could advocate and sign anti-abortion legislation, and in the very least could use the bully-pulpit to reach the hearts of the American people. That's in addition to his power to make appointments to the bench.
It should go without saying that electing persons with the greatest respect for life and the Constitution gives the greater likelihood that abortion is outlawed. Electing persons without that commitment reduces the probability to zero.
