The history books will record, ironically, that the Donald peaked in September 2018.
Obviously, that was the 10th anniversary of the Lehman financial meltdown. But the original event and its current commemoration actually book-end why Trump came out of nowhere, sojourned briefly in the Oval Office, and then fell victim to an even greater crisis that will end in ignominy for the Donald and staggering political and economic setbacks for the nation.
The original Lehman event was actually a symptom of the national economic breakdown which brought Trump to power against all odds. That is, decades of fiscal profligacy and egregious money-pumping by the Fed have deeply impaired and capriciously bifurcated the national economy and polity.
