The Massachusetts constitution was written much later than the other revolutionary state constitutions, and thus it avoids some of the earlier mistakes. The executive is stronger, with a limited veto; the senate is more formidable; and the judiciary is independent.
Gordon S. Wood[John Adams] experience with the French philosophers only convinced him further of the need for a bicameral legislature representing the two principal social orders and, equally important, an independent executive.
Gordon S. Wood[John Adams' writings] had indicted the United States for slavishly copying the English constitution by erecting bicameral legislatures in their state constitutions, most drafted in 1776.
Gordon S. Wood[John Adams and Tomas Jefferson] shared experience in 1775 - 1776 in bringing about the separation from Britain and their service in Europe cemented a friendship that in the end withstood the most serious political and religious differences that one could imagine, especially their differences over the French Revolution. It was probably Jefferson's obsession with politeness and civility that kept the relationship from becoming irreparably broken.
