I suspect there will be a “Red” state that initially attempts to tackle this cauldron of bullish*t. And like gay “marriage”, the battle lines will be drawn and the SCOTUS is going to have to decide.
The SCOTUS is arguably THE ONLY reason to support Glove. Although his judicial appointments here mostly sucked. OTOH, there aren't many GOPs to pick from here.
How could a state, as opposed to Congress, take the lead here? The issue is the language of a federal law and an anendment to the U.S. Constitution. Only Congress could legislate to stop birthright citizenship for children of illegal aliens, tourists and other non-residents.
