The walls supposedly are always closing in on Donald Trump. The end is always beginning.
He's going to quit. He's going to be impeached and removed. He's going to decide not to run again. Somehow or other, he's going to relieve everyone of the responsibility of ever thinking of him again, and especially of the responsibility of defeating him in an election.
This is the perpetual backdrop to media commentary about Trump. It rocketed around the internet a couple of months ago when Jeffrey Toobin of The New Yorker said Trump might not serve out his term.
