The GOP-controlled Congress have tried to wreck the USPS with a preposterously onerous demand for decades of future pension funding–as if the oil companies that get so much US subsidy had anything like that in place.
Now, by refusing to save the postal service as it goes into free fall, they will not only accomplish a long-standing goal but succeed in sabotaging mail-in voting, thus ensuring, so they hope, a Trump victory in November.
The Republicans are committed to destroying all public institutions in this country except the military. They can only produce societal destruction.
