Fundamentally, the mama-grizzly phenomenon is not really a movement or even a political term that represents a fully coherent set of ideas.
It’s mostly a marketing tool, meant to draw attention to Americans’ broad dissatisfaction with the way things are. Fair enough. Many people are dissatisfied, and they want to vent and they want to change Washington. But in the wild, real mama grizzlies are known to be aggressive, irrational, and mean. The issues facing the country are complex, and bears are not.
