Like Biden, I have always gotten someone's name wrong or at minimum misspelled names. With theoretical physics, I easily get lost somewhere between observable particles and the fields that are responsible for their partial existence. Some things befuddle me but I can usually ride the comprehension train for most things. I don't feel too old to use memory correctly. Biden has wisdom despite being a lifelong gaff machine, politically speaking.

In comparison, Trump is certifiable depending upon the physicians.

The glaring fact that in only four years! Trump increased the national debt by well over 8 trillion dollars is reason enough to reject him.
Clinton added 1.4 trillion in 8 years. Bush added over 8 Trillion as well as Obama over 8 years. Biden has added 1.2 Trillion so far.
