Which seems a rather apt lead-in to Trump; you may as well get your Godwins in early and accurately1.
So, is it a nash-in-ole fuckin' emergency? No, of course it isn't. The idea is absurd; no right-thinking person could possibly agree. Only in a nation with debased political discourse could such an idea even be briefly entertained.
However, as in all such things, Trump has people running cover for him. For example:
* Climate change is a national emergency.
* 28 million Americans without health insurance is a national emergency.
* Children in cages is a national emergency.
No. None of these things are national emergencies. They are all problems that you would like solved, but they aren't emergencies. And pretending that they are just provides cover for Trump and his fanbois.
I'm currently reading The Federalist Papers, which is largely Madison selling the proposed constitution by pointing out the numerous checks and balances. He isn't too bothered by the powers of what he calls the "Chief Magistrate"2, relying on the power of Congress (ironically, of the purse) to restrain him if necessary; and of course underlying all is the will of the people.
1. Hint: you can't invoke Godwin to mean "I don't like that" without looking silly.
2. I think he uses the term in a deliberate effort to play down the role. No nobility no king was a big thing at the time.
