I agree that one cannot compare this one and that of JFK.
Jackie was a traumatized young woman and no really complete plans could have been produced. Certainly cutting slack is exactly the gracious thing to do.
In reality there is no way even Jackie's good taste could compare with that of Nancy just based on age and tolerance for tradition.
Then there is the contrast of the quality of the two marriages.
God most literally blessed America with RR.
And his strong, loving wife Nancy. On that there can be no disagreement.
