in biden's defense - and, trust me, as i am sure you know, i hate having to defend this piece of shyt - it's naive to think voters will be swayed in any considerable fashion by his feeble appearance.
the electorate knows he's old. they also know, should he win re-election, he will be surrounded by younger people who will aid in the pursuit of an agenda that is the opposite of trump and his project 2025 insanity.
i am not convinced that idea of biden as a crotchety old man figures into the voting decision of anyone who isn't looking for an excuse to support trump.
