Fantastic suggestions, interesting discussion. If you didn’t read through the comments, the original prompt was, “Who could help the Democratic Party think about a ‘narrative’ that would help the party connect more powerfully with established, deeply historical, strains of thought and sentiment in American society?” My original response to the question was to suggest that public policy figures, experts, and political advisors are unlikely to be helpful for the most part, and I started off down the road described in my original post.
So here are other names from my list that didn’t come up in the comments, in no particular order.
Timothy Garton Ash
Henry Louis Gates
