Of course he knows the Dems won't cave easily.
Dens won’t cave as long as the SSS payments, ADC payments, Food Stamps, Medicare, Medicaid all continue. As long as it is the Armed Forces, Nat’l Parks, etc not getting paid they have no need to move. Not their constituency. I dont know about Fed LEOs, lawyers and such. I do know Mueller and his flying monkeys are getting paid.
