I've read their book, and I'm very sympathetic to the idea that American examples profoundly influenced European enlightenment thinkers. But "copied wholesale" seems unnecessarily strong wording. Clearly there's an influence, particularly in the 17-19 centuries. But there are other influences, and modern democracies have many features not present in urban centers of 18 century America. I don't see what the point is of disregarding the construction of parliamentary democracies based on voting, institutions, a free press etc, as an "implementation detail".
