Claiming “worst president ever”* ** requires knowing each president by name and having considerable knowledge of each president and the political, social, economic, etc. climate of their tenure to justify the comparative absolute.

It’s similar to climate doomsayers proclaiming “90% of all species on the planet will be extinct in 20 years.” To generate a percentage, one needs the total number of species currently alive. No such database is possible. Ever. And, one needs a workable mechanism to keep track of which species end (and a tally of new species) for the next twenty years. No such mechanism is possible. Ever.

Partial information isn’t the best endorsement of universal allegation.

*of the four presidents I know
**not including Lincoln
