Hillary Clinton’s campaign and her surrogates are so desperate to trip up a surging Donald Trump, they’re now accusing him of using illegal narcotics.

During the debate on Monday night, Clinton superdelegate Howard Dean speculated Trump’s sniffling was the result of using cocaine.

Notice Trump sniffing all the time. Coke user? — Howard Dean (@GovHowardDean) September 27, 2016

On MSNBC on Tuesday, he doubled down on the accusation.

“Why did you go there?” host Kate Snow asked Dean.

“Well, you can’t make a diagnosis over the television,” Dean responded, “I would never do that.

“But … that is actually a signature of people who use cocaine.

“I’m not suggesting Trump does,” Dean said coyly, before Snow jumped in saying, “But you are suggesting it, actually, in a tweet.”

“No, I’m suggesting we think about it,” Dean responded, attempting to split hairs.

“So he sniffs during the presentation, which is something that users do. He also has grandiosity, which is something that accompanies that problem.

“He has delusions — I’m not talking about being crazy,” Dean continued, “but for example, when he told everybody he was very smart not to pay taxes then denied he said it in front of 100 million people, it’s not that he’s delisiary about it, it’s that he thinks that somehow he’s not going to get caught.

“He has trouble with pressured speech … he couldn’t keep himself together,” Dean said.

He then speculated that because Trump is 70 years old, he “probably” does not have a coke habit.

“But I think it would be interesting to ask him and see if he ever had a problem with that,” Dean added.

Snow seemed to be visibly stunned by the doctor’s assessment.

“So as a physician and a medical person yourself, you’re suggesting that we ought to look at whether the Republican candidate for president has a cocaine habit,” she said.

“No, I don’t think he has a cocaine habit,” Dean responded, moments after speculating he “probably” does not.

“But again, I don’t make any diagnosis over the television. I think that’s wrong. Doctors shouldn’t do it,” Dean insisted.

“But I just was struck by the sniffing and then by his behavior,” he said, “which all sort of came together, these four symptoms.”
