If Reagan could not stop abortions, and the 2 Bushes could not even make a dent in abortions, I can not see ANY of the current crew being able to do it.
Only time abortions will subside is when WE THE PEOPLE RISE up in an overwhelming majority. Sadly, the country is badly divided. Abortion is freely available in almost every country out there. Only 6 countries in the entire world, the Vatican, Malta, Dominican Republic, El Salvador, Nicaragua and Chile make abortion illegal under all circumstances. It is legal in all others!
If SCOTUS rules 6:3 in favor changing Roe Vs. Wade, it could happen. But that is a long shot. Obama appointees are pretty young, and Ginsburg might retire in time for Obama to nominate another young justice.
I dare say Ginsburg may, um, visit Fort Marcy Park before Obama leaves office.
