I remember he wanted no Federal sponsoring of the abortion side of their work.
Some places might easily have 75-95% of their business to women be killing those babies though.
So in the end I don’t think planned parenthood will get more funding than what they could for non-abortive services.
All money is fungible. Whatever P P gets from taxpayers allows their donations to be used for abortions. Without taxpayer money, they would have to use some of their donations for non-abortion services, leaving less for abortion.
