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.

As early as 1776, [John Adams] expressed his doubts about America's capacity for virtue. "I have seen all along my Life, Such Selfishness, and Littleness even in New England, that I sometimes tremble to think that, altho We are engaged in the best Cause that ever employed the Human Heart, yet the Prospect of success is doubtfull not for Want of Power or of Wisdom, but of Virtue."

Perhaps more significant than his experience in Europe, though, was [John] Adams's experience in his own country, and his extensive reading on the history of the English constitution. In 1779, he had an opportunity to try out his ideas by framing the Massachusetts constitution.

[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.

The Declaration [of Independence] was a committee report, and [Tomas] Jefferson was simply the draftsman. [John] Adams's crucial role in bringing about independence in the Continental Congress has tended to get forgotten.

[John] Adams never had an optimistic view of human nature, and his experience in the Congress and abroad only deepened his suspicion that his fellow Americans might not have the character to sustain a republican government.

It was [John's Adams] Massachusetts constitution if anything that influenced people.
