And this was about a simple, one page document with a lot of public commentary (most famous being the Federalist Papers) and a promise of a Bill of Rights, which was fulfilled partially a couple years later, as the wikipedia article states:

Articles III to XII were ratified by 11/14 states (> 75%). Article I, rejected by Delaware, was ratified only by 10/14 States (< 75%), and despite later ratification by Kentucky (11/15 states < 75%), the article has never since received the approval of enough states for it to become part of the Constitution. Article II was ratified by 6/14, later 7/15 states, but did not receive the 3/4 majority of States needed for ratification until 1992 when it became the 27th Amendment.
