Like other forms of fascism, authoritarianism and reactionary politics, Donald Trump's so-called movement is a symptom of deeper problems in society, not the cause. Trumpism is not a boil that can be lanced, thereby ending the infection. It's more like a tumor growing from the bones.
It's not exactly true that the Republican Party was conquered or "taken over" by the Trump movement, as many observers still perceive it. The seeds of Trumpism were planted in Republican soil decades ago, and found it a hospitable environment. It's more accurate to perceive Trumpism as the next evolutionary (or, more properly, devolutionary) stage of the Republican Party and the overall conservative movement. It's where right-wing politics were going in America, whether leading conservatives understood that or not.
