Yes, I have been following this. He's a very doddery old f*ckwit who's had multiple moments in public (including just falling over when being questioned) when the lights are on but Mr Brain is not at home yet the MAGA's and the Fox News just don't report it. Donnie is the same - they don't comment. If this was a Democrat/Biden, they would be apoplectic.
In the same vein, demented Donnie gave an interview where he grabbed a book in a style that suggests depreciating co-ordination: interpreted by a dementia specialist as going back to basic grabbing instincts which is a natural default setting if you like. Also, Donnie struggles with any words of more than 2 syllabubs*....
*err, eh?
