This shutdown is a tough one. The Trumpists can use it to fast forward their plans to shut down most of the government altogether. The Dems can use it as the only leverage they have given their weaker position. Both sides kind of need the shutdown to happen to either move their agenda forward or attempt to put a "traffic moderation device" (road bump) in the way of the agenda.
No side is incentivized to compromise.
