I wouldn't mind seeing something like @BigDaddyKaine outlined. But I would make a contingency that "Sanctuary States" must surrender that declaration/status, birthright citizenship for children of illegal aliens after a specific effective date is GONE, and welfare is completely inaccessible to any illegal alien that has not been processed and brought up to date on their taxes. My sister in law is the freaking worst. 4 kids with 4 different absent fathers. Weighs 280+ pounds, lives a middle class lifestyle (cars, smartphones, cable, disney passes, vacations, etc) and hides all her money in the floorboards of her home so the government doesn't know she has an income. It's bullshit. Bleeds our tax dollars dry without contributing a cent. And it aint the kids' fault. I don't blame them for playing their PS4s and eating their pile of damn good food. They're kids with no control over the situation Not every family is like this. But the percentage who are can gtfo and adhere to the new rules.
