Yes, the first half definitely sounded like the beginning of a death announcement. I’m guessing they did that intentionally to point out his age and make us associate him with old age. They’ve been making lots of money off of Biden and Trump relating to age and whether someone so old is fit for office.
I, personally, don’t care about age. I care about values, performance, and ability to carry out the duties of the office. Bernie certainly aligns with my values, and has performed well in his terms. If he continues to have the cognitive abilities he has demonstrated, I’d support him until term limits were passed.
