Yes, but to be fair, also yes.
Harris' campaign mocks 'exhausted' Trump after he appears to nod off during an event
Trump's campaign has been responding in most of the articles I've cited recently. The response has been false, but it was a response. The fact that they don't have an answer for why Trump was falling asleep on camera is pretty damning. Trump personally responded when he was caught falling asleep in court, claiming he was closing his eyes so he could listen better.
Oh, and of course:
Yep, that's Tired Cancelling Trump calling Harris out for...I don't think she actually cancelled that dinner, I think she was invited and just didn't show up. Trump, by contrast, has flaked out a large proportion of recent events he said he would do, but lied.
He's cutting his schedule and barely able to speak in the ones he barely attends. Add "tired" and "sleepy" to the projecting terms Trump used against Biden.
WaPo has the headline "Trump's age finally catches up with him" proving that even WaPo isn't always great at investigation. Trump's been old and either senile or retarded for some time.
The people who have been screaming that Biden was too old have suddenly gone quiet. Possibly, they're asleep too.
