He did like a tenth of the press conferences as the last two presidents...
And people were pointing out his age related issues 4 years ago.
The only reason it took till the first debate for a critical mass to demand he drop out, was that was the first people had seen him speak for longer than 5 minutes. Ive been calling for him to do more public appearances/interviews this whole term, lots of us did. But we were called conspiracy nuts for saying an 80 year old was as capable as the average 80 year old.
The people around him day to day knew how bad it was and knew he'd be forced to step down if the public knew.
So they fucking hid him. Just like Republicans did with Reagan.
Like it or not, that's what happened.
I hope you at least learned that it's not just ok to criticize your "team" it's fundamentally necessary.
If people hadn't, wed still be running Joe and trump would still be likely to win.
