It's crucial that those of us (like myself) who are standing with Biden/Harris also recognize the distinct possibility that the President really is too frail to continue.

Here's what that means:

Most of the polls taken since the debate, treat all potential Democratic nominees as though they are interchangeable candidates. But the reality is that only Vice-President Harris (or the President himself) can seamlessly continue the current campaign.

Any nominee not named Biden or Harris would essentially have to build a new campaign from scratch, just months before the election. That is a practical impossibility, even if it were possible to choose such a nominee without fracturing party unity.

Given that Kamala Harris is polling as well, or better, than any other potential nominee, there is only one plausible path to a unified party and victory in November. That is to nominate President Biden, or for him to resign so Ms. Harris can run as the incumbent.

This is the message we have to spread within the Biden-loving activist community.
