Members of the California Nurses Association and supporters rally at the Capitol in Sacramento, Calif., in June, calling for passage of a single-payer health plan.

Never mind the raucous demonstrations it brought to the state Capitol in recent weeks, the “shame on you” chants in the hallways, the repeated unfurling of banners in the rotunda despite admonitions from law enforcement.
