Silver’s descriptions of what I think and of what the people who disagree with me appear to be thinking seem correct to me, but of course I know myself better that I know people who disagree with me. I think it would be interesting to have a leftist post about the division from his side’s point of view.
I think that the idea of “liberal” as an insult is driven by the conflict between these two factions, but I’m not claiming that they are the entirety of the Democratic party. There are others, such as organized labor and religious socially conservative black people, who nonetheless reliably vote for the Democrats. I’m curious about what group you would say that you belong to.
