There are so many quotes out there. I saw two that made me come up with this idea because he has been at the G7 on the world stage making a spectacle with his rambling. I did a search for a couple more just to give the post some more body.
It paints a pretty funny picture...
At the same time it is pretty scary. He is at G7 with these other world leaders and this is what they witness firsthand. What do they see that we don't find out about?
How bad might it be?
He didn't used to have these problems, and he did not have stuttering problems. He is clearly impaired and it should be no surprise since he is pretty old and has had brain surgery.
He is definitely a good example of an actual reason for the 25th amendment, though he should have never gotten this far.
He is a puppet. Puppets don't usually speak too well without someone there to do the talking for them (tell them what to say). He has difficulties even when they do tell him what to say.
The clue is there in how often he says...
"I'm going to get into trouble."
With whom? The puppet masters?
