I’d rather have the media talk about Biden than give Trump EVEN MORE attention. The psychology of advertising has shown that the cliche “All publicity is good publicity” is literally true on a population scale of at least a few thousand. Discussing Biden on the news cycle, positively or negatively, makes him more likely to win more votes. That’s why he will not and should not drop out now.
To be clear: I wish he had stepped aside for a different democratic candidate in 2020. But since then, I don’t believe there was ever a good time to shift attention to a replacement who would be popular enough to beat Trump.
