They're eating cats and dogs was straight demagoguery. It's like the Nigerian prince scams. It was rational for him to say that. Horrible, but rational.

Biden was in bad shape the way that a grandpa who has been running the family hardware business for fifty years gets a little bit confused about whether or not he called the guy about fixing the leaky roof, but by God grandpa is going to be at work seven days a week selling wrenches and screwdrivers and absolutely fucking refuses to take a vacation, let alone retire, even though there are younger people who are more than ready to take over.

Trump is in bad shape like a football player who got drafted out of high school, was hustled through his college classes on the basis of his football scholarship, and then took so many blows to the head that his brain looks like a dried lotus pod.

Neither is good, but there is a meaningful difference.

There is a difference between cognitive decline and just being a racist piece of shit.

"Beat medicaid" was cognitive decline. That wasn't a misspeak. His brain was mash potatoes that entire debate. That was just the funniest one. The really pathetic "sad slow confused old man" one's aren't as memorable.

Trump saying "eating cats and dogs" is literally just him being a racist piece of shit. That wasn't cognitive decline. Unless you think JD vance is showing old age cognitive decline.

Having said all that. They are both racist old white men with signs of dementia. The counter example you gave is just not a good example for Trump.
