I have no problem with the nit you’re picking at since there seems to be a lot of debate on these two patriots. From what I have read and been able to put together they were appointed as ambassadors primarily because they held similar status during the war. I have also read indications that some of the factions that constructed and gave us the Constitution moved to keep them there while the Constitutional Convention was being held. There were many who considered both Adams and Jefferson far too absolute and divisive in their views of government and freedom and feared that their inclusion would result in something other than the document we now hold dear. The heated divisions between the two in their personal dealings did not seem conducive to bringing together all of the states and factions under one, concise codacyl of law. For all of their passion and dedication to the new nation they would probably have been hard-pressed not to stand fast on each of their own entrenched opinions.
True. They were both what we, in our time, would term alpha males. Both stubborn, sometimes to a fault. Both dear friends to each other, and dear enemies. So strangely intertwined were their lives that they died within hours of each other on the same day, July 4, the 50th anniversary of the signing of the Declaration of Independence. The odds against that must have been astronomical. :)
