Has anyone seen proof Biden isnt an android? He seems to suffer BSOD regularly
He has a bad stutter since childhood which he has mostly overcome. However sometimes it pops up and he has taught himself the signs that it is coming, pauses and comes up with a different word.
For whatever reason his minders seem to think that perception of loosing thought process is a better bet than stuttering in public.
Probably doesn't explain it all though.
