Krystal Ball’s commentary is spot. The Left constantly ignores Joe Rogan’s many left-leaning positions and it’s to their own detriment. One problem is that Joe is too damned independent and doesn’t pass the left’s political purity tests. Krystal also suggests a time-of-genesis and a motive for this dysfunction: Joe’s words in support of Bernie Sanders during the primary.
This exposes a real weakness in the Left: An inability to accept allies where it finds them. If you cannot accept support when it is offered, you are eventually condemned to a fringe movement.
