The demographics do indeed work in Democrats’ favor. Democrats need to think about how they will govern when there are no longer any Republicans in the way of their projects. Which projects actually make sense? Which ones are affordable, for real, not just when an election is in the offing?

How can primaries be made fair, when only the primary contest matters?

Democrat-run one-party states and cities are a good place to look for both worked examples, and cautionary examples. Mostly cautionary examples, but Oregon would qualify as a worked example, as would Austin, TX and Boulder, CO.

Chicago—-cautionary example. Illinois—-cautionary example. Hawaii—-worked example, but not one that any other state can emulate.

Looking further afield, nations that are more or less democratic, but field only one party with any real shot at national power, haven’t done that well. The list of cautionary examples is long and sobering.
