How Salutary Will Be the Interference?

It's as if James Madison, writing in March 1788, was using some device to peer 228 years into the future when he wrote the following in Federalist 63.

"[T]here are particular moments in public affairs when the people, stimulated by some irregular passion, or some illicit advantage, or misled by the artful misrepresentations of interested men, may call for measures which they themselves will afterwards be the most ready to lament and condemn."

"In these critical moments, how salutary will be the interference of some temperate and respectable body of citizens, in order to check the misguided career, and to suspend the blow meditated by the people against themselves, until reason, justice, and truth can regain their authority over the public mind?”

How salutary (beneficial) the interference--that is the question, isn't it? Safe to say, already, 39 days before inauguration day, that Trump will not sane-up and spare the republic this challenge.
