Twenty days in, and the leaders of a divided federal government have reached total breakdown. The dramatic theater of Wednesday aside, with each passing day it has become increasingly clear that President Donald Trump won’t — and thinks he can’t — buckle on his wall demand. Democrats won’t — and think they can’t — buckle on their refusal to give him money for the wall. Meanwhile, hundreds of thousands of federal workers miss their first full paychecks Friday, and the bite of the shutdown grows daily. This is, to be blunt, a mess.
