The moderate gray area between Republicans and Democrats is disappearing. Like a zygote dividing we are becoming two countries. The smartest way to go for Republicans is to call a rump Congress in some Midwest location and vote to Expulse the Blue States for high crimes and unconstitutional actions such as creating sanctuary cities and states and ignoring and violating Federal Law. And they don’t get to keep the whole states. Instead the red counties are kept as a new state or merged with an existing state. A blue state like Illinois would then exist as a red state and the Chicago counties would be expulsed.
Once separated tariffs can be applied to goods and services provided by the reconstituted United States and the Expulsed blue Cities and States. If it is made onerous enough the illegals will return to their countries shrinking the population problem.
Great idea for political fiction. Too bad Republicans lack the balls to even consider such an attempt.
