Ensoulment is spiritual, personhood is constituional/legal and the 3/5 compormise was devised to prevent slaveholders from having extra power (the abolitionsists wanted slaves to be uncounted at all). Abortion is killing. Whether that killing is murder is a legal question, not a moral one. It was not considered murder before Roe. Abortionists were fined for violating medical canon. Like shooting your neighbor's dog. You cannot make abortion murder without going after mothers and making all feotal deaths a public event. Society will not go there and state law is not allowed to try. Good luck with the Senate. It won't eve pass Trumpcare, let alone feotal personhood. We already give parents child tax credits, they are simply not big enough (and Ford was the one who proposed them). Probably the only chance at tax reform is a much larger child tax credit. Easier to pass than making desperate women behave or the conservative parents of girls caught pregnant.
