Trump and the MAGA crowd keep harping on Bidenās mental capacity while Trump (several times) confuses Biden with Obama and is confused about WWII. And he keeps bragging about how he āacedā the routine Medicare cognitive test, which asks one to remember five things and say then back. āPeople were amazed I could do that.ā Well, not those who have taken that test, like I have. My doctor wasnāt amazed that I passed it. He would have been amazed if I didnāt!
