My guess is probably bring the full weight of the city and state police forces to crush them. And then seize the properties and let the illegal immigrants stay. Those rules and actions of course will not apply to Demscum connected "elites."
Maybe a little hyperbole here, but I'm no longer certain.
Neither am I.
They will probably bologna-slice he property rights away. Just as what liberals want is not called socialism, even they want wealth-distribution, to upwards of 99% if your income, and regulate your business to such a point that you make no decisions. They will do the same with your property-rights. Only along the most technical merits will you have property rights, but not really.
Socialism, without calling it socialism.
