Yes, Atrios calls this – “The president is an addled old guy who spends most of his time watching the President Trump show on teevee getting increasingly angry that the President Trump character isn’t the dapper, noble, and beloved hero he is supposed to be.

And then he lashes out by yelling at people on the internet.”

Sometimes he lashes out in the offices of the WH.

The rest of the time he’s doing the inexcusable and the inexplicable and having it excused and explained by his paid lackeys (sad, but almost understandable) and by GOP electeds (just as inexplicable!)

He likes to give interviews, even when he should just shut up and disappear for a while, so that’s fun.  He gave one to the Economist.  The Economist, mind you.

Yes.
Have you heard that expression used before? Because I haven’t heard it. I mean, I just…I came up with it a couple of days ago and I thought it was good. It’s what you have to do.

He thinks he invented the term “prime the pump.”  It is to laugh.
