Why are you making this about Republicans? They'll never be able to "defund" Planned Parenthood. And even if they did, PP only gets 33%of its money from the feds. they'd make that up with contributions or whatever.
Bottom line, they, ACA, and cheap rubbers at 7-11 (free in some places) should be able to cut way down on unwanted pregnancies. I don't understand why we have so many these days with all the free/cheap contraceptives available.
