Yelling at people to silence themselves about Biden's health is not going to work. The only way the story goes away now is if he resigns.
I wish that weren't so, but wishes aren't facts.
It wasn't "going away" even had the debate performance been flawless. But the narrative is now going to dominate coverage both in the right-wing gutter press and "objective" MSM. I sadly don't think Joe can win anymore. The coverage will make emails look like a single-day one-off on page 12.
If Biden stays in and ends up losing to Trump, I don't want to hear anything from Dem partisans about it being the fault of "progressives," or "young voters," or "Jill Stein." They have an easy, obvious out and they aren't taking it. It is 100% on him and the campaign.
