The Democrat slush fund is hereby diminished.
Right, but it goes beyond just the money paid to Democrats and their causes. Bloated public sector unions keep lots of people on the payroll who basically function as professional agitators/protesters. When you see those nutbag rallies, you can be pretty sure that there are a lot of hired union goons in there.
This is going to really hurt those unions in the pocketbook, and that means they won't be able to keep nearly as many of those people on the payroll. Those bogus "grassroots" protests, particularly in cities, will lose a good chunk of their activists.
