Ann Landers, the late advice columnist legend, used to say that somebody was “several sandwiches short of a picnic.” Keith Olbermann is less cryptic when it comes to President Trump: He thinks he’s a sick puppy.

Nor is he alone. “People on the inside say he keeps getting worse—and mentally, keeps getting worse,” MSNBC’s Joe Scarborough said Tuesday on Morning Joe. “This is, unfortunately, not a learning curve. This is a man in decline.” Carl Bernstein, the legendary Watergate journalist, told CNN‘s Brian Stelter on Sunday, “We have many reporters, myself included, who have talked to numerous people, Republicans on Capitol Hill, who in private will tell you they doubt the stability of this president.”

“It’s part of the story,” Bernstein says, ”and it’s very hard to cover.”

Not that it would stop Olbermann. Not long after Trump bemoaned that he was treated worse than any politician “ever” during a Coast Guard Academy appearance, Olbermann was taping a segment for GQ and declaring, “Donald Trump is not well. Some kind of paranoid delusion.”

Perhaps it’s prompted by some psychiatric condition, illness, substance abuse, maybe the long-term consequence of a concussion, he said.

“As a whole the country has been unwilling to consider this as a possibility,” he said, suggesting that most people “don’t want to confront mental illness.”

But it’s a matter “of whether the equipment works.” As a placeholder, maybe just tag him “crazy.” (@KeithOlbermann)

He quoted a Washington Post piece citing a “GOP figure close to the White House” who wonders whether Trump is “in the grip of some kind of paranoid delusion.”

“You think?” said Olbermann.

Ah, were Landers around. Imagine:

“Dear Ann: You’ve been great in warning us all of the importance of mental illness and the need to not stigmatize those with the disease. It’s no different than in being empathetic to those with any illness.”

“But, that said, is the president nuts?”

John Dean said famously there was a cancer on the Nixon presidency. At minimum maybe there’s a new procedure, a Trumpectomy, that can root out the problems here. For the nation’s sake, hopefully the White House ills aren’t metastatic.

The 25th Amendment?

New York Times columnist Ross Douthat argues that one should go after Trump using the 25th Amendment, but University of Chicago Law professor Eric Posner blogs that it’s a bad idea:
