The New York Times reports on Trump's mental state:

With Mr. Biden out, Mr. Trump, at 78, is now the oldest major party nominee for president in history and would be the oldest president ever if he wins and finishes another term at 82. A review of Mr. Trump’s rallies, interviews, statements and social media posts finds signs of change since he first took the political stage in 2015. He has always been discursive and has often been untethered to truth, but with the passage of time his speeches have grown darker, harsher, longer, angrier, less focused, more profane and increasingly fixated on the past.

According to a computer analysis by The New York Times, Mr. Trump’s rally speeches now last an average of 82 minutes, compared with 45 minutes in 2016. Proportionately, he uses 13 percent more all-or-nothing terms like “always” and “never” than he did eight years ago, which some experts consider a sign of advancing age.

Similarly, he uses 32 percent more negative words than positive words now, compared with 21 percent in 2016, which can be another indicator of cognitive change. And he uses swearwords 69 percent more often than he did when he first ran, a trend that could reflect what experts call disinhibition. (A study by Stat, a health care news outlet, produced similar findings.)

Also, contrary to Kilmeade's claim of sixty to a hundred thousand, an estimated 24,000 people attended Trump's rally in Butler.
