Since I haven't received even an attempt at an answer to this question before, I'll ask it again: what evidence does anyone have to show that Biden's age has negatively effected his mental capacity? I'll concede that his age is a reason to ask the question, but the question keeps being repeated in spite of any demonstration of mental lapses on his part. His verbal gaffes have been consistent throughout his political career, and I've seen no evidence that they've increased in his old age.
Has anyone attempted to dispute this? Is this why it keeps getting brought up? And how has his age affected his capabilities? Give me specifics, please.
I pointed out in another thread that Bernie Sanders is a year older than Biden, yet nobody questions his age or competence. Media is trying to manufacture loss of confidence and it pisses me off.
