Jennifer Rubin gets it:

"1. The pundits' arrogance is off the chances. That materially reduces the chance Biden would ever leave. 2. They do not matter. It drives them nuts that Biden has contempt for them. 3. the ONLY way this changes: the polls collapse, Jill says enough, the entire DNC and the delegates switch to Kamala Harris with no fuss, no muss. 4. The chances of #3 in the Dem Party (we are talking Democrats folks) is about 1 %. Not zero but tiny.
