I can see that concern but a couple things I think are worth highlighting (and for starters I’m not the submitter).
I and everyone else who’s calling for Biden to step down are equally concerned for a Trump presidency.
We simply believe all the data points to an inevitable Biden loss, in addition to down-ballot races. Clearly Democratic representatives running tough races agree.
We can’t put the cart before the horse and deal with Trump until we actually have a viable candidate first. I and many like Biden and his administration but know he cannot run a successful campaign, and again, data shows it.
Once this is settled, normal scheduled programming will resume and all focus will be on how bad Trump and the GOP is.
