Assuming he loses this fall, there's still going to be an immense amount of recovery work needed (how's that for an obvious statement?).
From the link:

...what do we do to undo Trumpism? Not just to counter the destruction Trump has wrought, but the decades-long preconditions that made his election possible, if not almost inevitable.

The lesson Feffer draws is a tough one: "Today's Republicans, the equivalent of the northern Democrats of the post-Civil War era and a true confederacy of dunces, cannot be allowed to persist in their current incarnation as a vehicle for Trumpism."
...
Feffer also ties this point to the example of Nazi Germany and the Nuremberg trials, where "the Allied victors put nearly 200 Nazis on trial for various crimes: 161 were convicted and 37 sentenced to death." To follow this example, Feffer suggests that federal prosecutors should prosecute Trump and his top associates as a criminal enterprise under the Racketeer Influenced and Corrupt Organizations (RICO) Act. Doing so could "not only remove him from the political equation but could effectively delegitimize Trumpism and prevent a second round of it from occurring."
