He’s no JFK or Obama when it comes to public speaking but he certainly doesn’t come across as senile, and I suspect I have more experience with senile people than you have. Being a bit forgetful and being prone to the odd gaffe makes him like 90% of the population.
I don’t want to go into it too much but my experience is with a close family member, who I saw every day, who died of what caused him to be senile, so you must be qualified professionally if you’re beating that.
I also have personal experience in his excuse for it, having a stammer, growing up with one myself and spending hours in speech therapy, still having it as a burden but ultimately controlling it now.
If you think his cognitive ability is similar to 90% of the population then that’s an opinion I cannot agree with.
I don’t dislike the guy for it, it’s sad and I wish him all the best and still think he’s a better candidate than Trump to run a country, most people are, Im just saying I think he is going senile.
