Your intellectual dishonesty is disgusting. Fred is not "borrowing" a position from McCain. He is advocating a return to the legal framework of abortion law that existed in this country for over 200 years prior to Roe vs. Wade. John McCain didn't invent the position on Goerge Stephanopoulos' show.
IN 1973, we didn’t have 4-d ultrasound, we didn’t have detailed knowledge of the human genome, we hadn’t figured out how to clone things, and we rarely saved a baby born much before normal gestation.
We know a LOT more about the personhood of the pre-born than the founders knew, or than we knew when Roe hit. Roe is an enshrinement of scientific illiteracy.
