Trump Derangement Syndrome is a phrase used by many supporters of former President Donald Trump to describe those who have unreasonable responses to anything he does, but it may be a real issue.

Presidential historian Mark Halperin spoke to former Fox News host tucker Carlson where he said a defeat of Vice President Kamala Harris by the former president could trigger the worst mental health crisis in the history of the nation.

“A lot of Democrats, maybe the majority, believe that Trump becoming president again is the worst thing that could ever happen. So how do they respond to that?” the host said.

“I say this not flippantly, I think it will be the cause of the greatest mental health crisis in the history of the country. I think tens of millions of people will question their connection to the nation, their connection to other human beings, their connection to their vision of what their future, and the future for their children, could be like. I think it will require an enormous amount of access to mental health professionals. I think it’ll lead to trauma in the workplace. I think there will be some degree of –,” the historian said before the host cut him off to question if he was serious.

“100% serious. I think there’ll be alcoholism, broken marriages… yeah. They think he’s the worst person possible to be president. Having won by the hand of Jim Comey and a fluke in 2016, and then performed in office for four years, and denied who won the election last time, and January 6th… the fact that under a fair election, America chose by the pre-agreed rules Donald Trump again — I think it will cause the biggest mental health crisis in the history of America,” Halperin added.

“And I don’t think it will be a passing thing that, by the inauguration, we’ll be fine. I think it will be sustained, unprecedented, and hideous, and I don’t think the country’s ready for it,” he said.
