The right requires the machine in order to maintain their propaganda about bringing down the machine. They don't want to get rid of drugs, or undocumented people. They want to take undocumented people one-by-one off the street, so there's a constant "need" to continuously ramp up authoritarism.

The end of undocumented immigration would spell disaster for the Republicans, and they know that. For many red states, it would be literal economic disaster, even if we look past the messaging.

So it's flashy non-solution after flashy non-solution.
