This author articulates what they wish the current jurisprudence to be. However, that is not reality and as my father was fond of say “Wish in one hand, spit in the other and see which one fills up first.”
I don’t like birthright citizenship and would gladly support a repeal/replace of the 14th amendment. But anyone who thinks that the current SCOTUS, Congress, and President will do anything to change the current jurisprudence is simply fooling themselves .... and wishing in one hand.
All that is needed is a bill passed by congress and signed into law by the President. Text of law: “Childern born in America to a (certain class) are not citizens.” It works same way as current law for foreign diplomats, just fill in ‘certain class’ with ‘illegal aliens, foreign nations legally visiting etc’. The 14a doesn’t need to be touched.
