polls-as-propaganda are trying hard to pitch this as a democrat led shutdown, but that's real hard for people to square with the GOP owning all 3 branches hard. especially with Trump's perennial victory lap and his insistence since the election that he is the undisputed leader with all the power.
Even if it was the democrats shutdown, what do they have to lose? FUCK THEM UP! Drowning? Drag them down with you. Become such an obstruction that they have to beg and give you half your wants before even sitting at the negotiating table.
