Jakub,

Democrats have been offered an opportunity to change their nominee. Although late in the day, the moment should be seized.

Allow Joe Biden 24 hours of mourning, then insist he stands down from running for a second term (he likely won't volunteer).

Then, immediately set up an open process for selecting a new nominee, including debates, town halls, etc.

It will be exciting, invigorating, and winning.

Best.
