,,,when it comes to the postal service. Rightwing Republicans are always going on about the Constitution and The Founding Fathers, but it was the Republicans who semi-privatized the U.S. Postal Service which led, in part, to the situation now, where post offices are closing and hours of delivery being cut back, and other changes for the worse for those who still rely on the mail for many things (i.e. the poor who don't have access to computers and smart phones, and those not-so-poor who haven't succumbed to the Internet's lure).
The U. S. Postal Service was established in the Constitution, one of those very specific articles there, and further honed by The Founding Fathers in the years after that article was ratified. So, in order to provide for the general welfare of all its citizens, the U. S. government should be able to run the Post Office with revenues from taxes as well as postage and other fees. But like the country's railroad system(s), rightwing Republicans have managed to decimate the Postal Service, as well as the rail lines (which can be justified by the Constitution in several ways, but one of them might be the section about "postal roads" being built and maintained, since a lot of mail has always traveled by mail).
And they've done this while subsidizing, with our tax dollars, big banks, oil companies, weapons manufacturers, billionaires, etc. etc. etc. (which is nowhere supported in The Constitution).
But as post offices disappear, and those of us who still use the mail get forced to turn to "for profit" carriers like UPS and FedEx (the U.S. Postal Service was not meant to be "for profit" until the Republicans changed it to a semi-private corporation back in the '70s), rightwing politicians will continue to tout their proprietary claim on The Constitution and The Founding Fathers as if the rest of us can't read or don't bother to, so will never realize what hypocritical liars they can be and often are.
