The courts are the one thing the progressives must keep. When they lose elections they sue until they find a judge to change the outcomes. When they win, they have a court cement their unconstitutional power grabs. When they can’t pass a law they find a judge to declare laws. They are losing their power, they hate Trump. They hate the people that voted for Trump and want to punish them. The courts are a powerful tool in their arsenal.
The rats screwed up assassinating Scalia, and they know it.
