Some inside baseball from the Trump campaign . . . Joe Scarborough and Mika Brzezinski have known Donald Trump for years, and reportedly are in regular contact with members of his campaign staff.  On today’s Morning Joe, Scarborough said that what: “every Donald Trump staffer will tell you is: he never, ever takes any of the blame himself. He always screams at staffers. That’s what is starting to happen now that the polls are going low.”

Meanwhile, Mika Brzezinski reported that Trump is exhausted, sleeping in “two-hour spurts,” and that as a result Trump is “losing it.” Do Joe and Mika have any sources inside Hillary’s campaign? Think Clinton might occasionally raise her voice? And if she isn’t sleep-deprived, what’s accounting for her physical and verbal stumbles? Short-circuit, anyone?

JOE SCARBOROUGH: The bitter truth for these [down-ballot] candidates is, not only does Donald Trump not care whether they win or lose, people in Trump’s own staff are starting to say, he’s going to lose, he’s going to blame us and he’s going to throw us overboard

MIKA BRZEZINSKI: And they can’t help it because they don’t know what they’re doing —

JOE: — one thing every Donald Trump staffer will tell you is: he never, ever takes any of the blame himself. He always screams at staffers. That’s what is starting to happen now that the polls are going low.

MIKA: People getting kicked off the train.

JOE: Forget Ron Johnson, forget Mark Kirk, forget Kelly Ayotte, forget the Republican senators across America. Even Trump’s own staff is now awakening to the fact that he’s going to blame them for the stupid things he says and they’re going to be out of luck after the election.

. . .

JOE: So Mika, you and Bob [Costa, of the Washington Post] were talking in the break and you have a theory, and I think you’re dead on, for people that know Trump, about why he is getting even more erratic on the campaign trail. Especially at night.

MIKA: Well, from knowing him over time, this candidate is not the person that we knew. And I think he’s absolutely exhausted. I don’t think he’s slept. I don’t think he’s slept since he won the nomination and even before when he was starting to realize that he was going to win the nomination. I think he sleeps in, from what I’ve heard, two-hour spurts. And that takes a toll on the brain, in a very real way. It impacts your judgment, it impacts your mood, it impacts your ability to connect with people, it impacts your ability to obtain and take in and process information. I think he’s losing it.

JOE: And then most importantly, Bot, it impacts your decision making process.

BOB COSTA: About a year ago I suggested to Trump that he’s at his worst at times when he’s exhausted. He really balked at that suggestion and he said I’m so high energy. So I think this is how he sees himself. Always high energy, always on, even if he is tired.
