The spotlight is now on Biden's mental ability.
What about Trump's?
In an interview with Dr. John Gartner, who was professor of psychiatry at Johns Hopkins Medical Center for 28 years:
"I asked Gartner whether he perceived any difference between the cognitive ability of Joe Biden and Donald Trump. Absolutely, he replied. “It’s like comparing apples and rotten oranges.”
There’s a huge difference between the two, he said. “Biden is aging. Trump is dementing.” "
