TRUMP; CAN CORRECTLY RECALL MANY EVENTS FROM LONG AGO, WALKS QUICKLY AND EFFECTIVELY WITHOUT ASSISTANCE, AND HIS MISSPEAKING MOMENTS ARE FEW AND FAR BETWEEN; HE OBVIOUSLY HAS DEMENTIA. INVOKE THE 25TH! BIDEN; REGULARLY MISSPEAKS AND MUMBLES INCOHERENTLY, MOVES AROUND LIKE A 2-YEAR-OLD LEARNING HOW TO WALK AND RARELY DOES SO WITHOUT ASSISTANCE (AND STILL LOSES HIS BALANCE ALL THE TIME), SOMETIMES GOES ON RANDOM BELLIGERENT RANTS FOR NO REASON AT ALL, WAS LIKELY SUFFERING FROM CANCER FOR HIS ENTIRE TERM, CAN'T EVEN CORRECTLY RECALL HOW HIS OWN SON PASSED AWAY... SHARP AS A TACK!
