The degree to which the Republican grandees have abandoned the Constitution is revealed in their justification for suppressing mail-in voting:
If we allow mail-in voting, no Republican will ever be elected President.
Hello: last I checked, the United States was a representative democracy. That means that dogmatists can expected to be checked by the will of the people. When your policies make you unelectable, you need to change your policies.
In other words, what the Trump, McConnel, and their ilk are saying is “if we want to have another Republican president, we will have to abandon our corrupt crony-capitalism Federal racket.”
Which, actually, is just fine by me.
