I don’t know how to explain to our nation’s top editorial boards that the Democratic Party is an actual organization with a lot of rules and history to it, not just a store that distributes team jerseys, and it has already selected delegates to its nominating convention.
Both parties make or interpret rules as needed, to suit their interest in the moment.
Of course I would prefer the rule of law, but that has been a fiction without normative power for a while now, in this country.
