 I mean, I think it makes sense that Jack is highlighting Biden's record prevailing over worries about his age, while Joe is criticizing the same issue here. And throughout the campaign, we've heard concern about both these men's ages. They're pretty similar in age, but Biden is a few years older and it has been a bigger concern. The Biden campaign has pushed back against that concern and said, look at his record, look at his political tenure. But this debate was an opportunity to assuage some of those worries.
