One of the most famous clues in a Sherlock Holmes mystery is what’s commonly referred to as “the dog that didn’t bark” or, as Holmes actually said, “The dog did nothing in the night-time.” Rasmussen Reports, which puts out a Daily Presidential Tracking Poll like clockwork, noticed that its competitors ceased barking (or, if you prefer, polling) after the two parties held their conventions. According to Rasmussen, which would know, this silence was unprecedented.
Rasmussen published a series of tweets on Monday openly snarking at its competitors for their silence. Moreover, whoever is writing Rasmussen’s tweets was not shy about identifying a reason for the other polling outfits’ unusual reticence: The narrative up until the conventions was that Biden was unstoppable; it’s now quite possible that he’s been stopped.
