For John, BLUF: It isn't over until it is over. Nothing to see here; just move along.
The Commonweal Magazine has an article by Columnist E J Dionne, Jr, titled "The End of Trump: What His Miserable Week Confirmed". That was Monday, 4 April. And Mr Trump lost in Wisconsin on the 5th. But, it is on to New York.
I am not sure Mr Dionne has a clue, as I noted in a comment at the Commonweal Magazine web page.
Even if the end of Trump is coming, the end of the causes of "Trumpism" is not. The Republican Establishment (and the Democratic Establishment) need to reform. And it would help if the Media would not cover for the Establishment, but expose it as the People see it.
