President Biden has repeatedly and correctly described the stakes in the presidential election as nothing less than the future of American democracy.
Donald Trump has proved to be a significant threat to that democracy, systematically undermining election integrity.
Biden has argued that he is the candidate best able to face this threat and defeat it.
Biden has had difficulty explaining what he would achieve in a second term.
The greatest public service Biden can currently offer is to announce that he will not continue to run for re-election.
Americans are seeking fresh voices to take on Trump.
The Republican Party has been co-opted by Trump's ambitions.
The burden of offering a strong candidate falls on the Democratic Party.
Conclusion: The clearest path for Democrats to defeat a candidate defined by his lies is to deal truthfully with the American public: acknowledge that Biden can't continue his race, and create a process to select someone more capable to stand in his place to defeat Trump in the upcoming election.
