my claim is a simple one ..... the most authoratitive studies that we have of the evaluation of the presidents are done in several studies - two by the Schlesingers, one by the Wall Street Journal, among others.
I am not claiming that these are the DEFINITIVE LAST WORD on the subject or that they are infallable. Simply, that they are the best we have from the best minds we have available to make such judgments.
If anyone else has other authoratative studies of the same topic, I would be glad to examine them. So far, I have see no such presentation here or anywhere else.
Until that happens, I hold these, and academia holds these, to be the best we have available at the present time.
That is why they are quoted in reference books along with the usual information about the presidents. They are the best tools we have presently for evaluating the presidents.
