Why not pass the law and see how the courts decide. A Constitutional amendment might not be necessary. There are two bills now in Congress since January, one in the Senate sponsored by David Vitter and one in the House, sponsored by Steve King, HR 140, that eliminate birthright citizenship. Someone should ask Cruz if he supports these bills.
Dear leader will just veto a bill like this and then it will fail to get a majority to override the veto - the DEMS will block it and I’m sure we can count on some of the RINOs to vote with them.
