No matter how you slice it, the really raving base (for any of the 4 reasons mentioned in the article) is probably around 10-15 million people, and gradually declining. We will never get any significant number of those votes. But > 4 times that many cast a vote for him, and that is on us for not presenting a clear and acceptable alternative.
And after all of this, we still have no clear leadership and messaging, especially from the DNC or the Congressional leadership. The clearest messaging is coming from Newsom, and he is putting it in terms that Americans can connect with.
I compare Newsom and Schiff. I have the greatest respect for both of them and don't question their integrity, patriotism, acuity or anything else. But when Newsom communicates, it leaves a mark. When Schiff communicates, it is really cringeworthy, like a dry college lecture on a subject nobody really wanted to be studying in the first place. Totally in the abstract. That's OK. We need people like Schiff in Congress, and in a normal world, maybe his type of aspirational abstractions would be OK. But that will never work with where the public is today.
