Ronny Jackson, former White House doctor, predicts Biden will resign

Rep. Ronny Jackson (R-Texas), the controversial former White House physician, said on Thursday that he believed President Biden would resign because of his limited cognitive abilities.

During an episode of Fox’s “Hannity,” host Sean Hannity criticized responses Biden gave during a CNN town hall the day before, calling some “completely incomprehensible.”

In an interview with Jackson, Hannity said that Biden would not perform well on a cognitive test, repeating a claim circulated among Republicans that the president's health is in decline.

Remember this?

From Vox (in 2018) - 

White House doctor: Trump “has absolutely no cognitive or mental issues”

President Donald Trump is in “excellent” physical and cognitive health, according to his physician Dr. Ronny Jackson, who shared the results of Trump’s first physical at a press conference Tuesday.

“It is called genetics ... ” Jackson said. “Some people have just great genes. I told the president that if he had a healthier diet over the last 20 years, he might live to be 200 years old.”

Trump’s only health concern, according to Jackson, is his weight of 239 pounds. Jackson said the president wants to lose 10 to 15 pounds over the next year, and plans to exercise more.

His expertise on the topic of "cognitive issues" is questionable, and, while Trump may be the 6'3'' described in the Vox story, *I'm* closer to 239 pounds than Cheeto, and I should lose more than 10 to 15 pounds.

For the record, I am not questioning Cheeto's mental state.  The cabinet didn't 25th Amendment his ass; and they saw him more closely than a TV camera, and they saw him every day.

Plus, being found to be mentally unfit would keep him out of the place that he so richly belongs, prison.
