The Washington Post cannot see that this is not a poll about Biden but instead a poll about journalism and its failures to inform the public. Polls are their self-fulfilling prophesies. They are damaging to public discourse.
Read the poll itself: leading questions that lead inevitably to the headline. This is not public discourse. As James Carey said, polls preempt the public discourse they are meant to measure.
