He would absolutely do that if it suits his agenda. Branding it as "empowering the nation's police" or some bullshit like that will make the thin blue line crowd that constitutes a large chunk of his voters happy.
A good chunk of restaurants will also suddenly close or have massive price hikes when they can't count on taking advantage of undocumented people and paying them sub-minimum wage off the books.
I hope he wins. Hell I’ll vote for him. Anything that speeds the collapse and frees minds. “Leftist” capitalists are ruining the entire planet. Vote for the bad guy. Hasten the fall.
