Our friends at Mediaite flagged down quite the exchange on the Thursday edition of MSNBC’s The Beat in which comedian Sinbad declared that the current incarnation of Donald Trump is “post-dementia Donald Trump who just loves picking fights cause...he’s a lonely man” and one of many “keyboard gangsters” on Twitter who are far less tough in person.

Host Ari Melber first observed to Sinbad in a taped interview that “Donald Trump seems to obsess over a lot of people who come out of the culture who have either success, fame or credibility” and thus wondered: “Why do you think he's picking some of these fights with everyone from the NFL to de Niro?”

Sinbad responded that he’s noticing “two different Donald Trump[s]” with the first one being from the 1990s “that did all the fights, I was doing the casinos where you Mike Tyson there, you had, you know, Don — Don King promoting the fights” and “hanging out with hip hop cats.”

As for the current incarnation, Sinbad argued that Trump’s “post-dementia” and “just loves picking fights cause I think he’s a lonely man” who “never really had a lot of friends” and thus “wants to be popular.”

“He wants to be a celebrity and he loves being able to Twitter slam people because you don't have to see them face to face. He's not good with that,” he added.

Melber invoked Drake to inquire if Sinbad agreed with the rapper’s assertion that “people with Twitter fingers sometimes aren't as hardcore when you meet them in person.”

Sinbad agreed, dubbing Trump one of those “keyboard gangsters” that “wouldn’t hurt a fly” since “they live behind the keyboard.”

When it comes to explaining why Trump ran for president, Sinbad gave his best analysis, including the claim that he had to have had some sort of “mental deficiency”:

No. The win for him was to get a show, to go almost to the goal line, not win, pull up a hamstring move — pull a hamstring and to get your TV show, cause he could have always said. I could have won. I could have won. They didn’t want me to win. I’m too good. I’m too truthful. I’m too different. See, it’s easy — it takes the perfect trifecta. You got to be rich, I mean, filth rich where you don’t need the job, you can throw anything out there, you don't care and then you’ve got to have a little of a — a mental deficiency.

On the subject of Sinbad, he was a passenger on Hillary Clinton’s infamous trip to Bosnia and did not agree with Clinton’s recollection of coming under sniper fire, recalling: “I think the only ‘red-phone’ moment was: ‘Do we eat here or at the next place.’”
