 That concern, that feeling that Biden really should step back, as messy and unprecedented as that would be, is pretty wide. The level of concern among Democrats, not only that they're going to lose the White House to Donald Trump, but that they're going to lose control of the Senate and that they will not regain control of the House. It will be a catastrophic election year for Democrats with Biden at the top of the ticket. That is the view of a significant number of Democratic officeholders.
