Note: States with at least one delegate present had one vote each. The Convention had been called by Congress, so the delegates that went home were actually abstaining from voting within their state's caucuses. Therefore, the final vote to approve the draft and send it to Congress was 12-0. Congress then sent it to the state legislatures for ratification (or rejection). Ratification required 9 states. The Constitution went into effect with ratification by New Hampshire on June 21, 1788, leaving New York, North Carolina, Virginia and Rhode Island out in the cold. But Virginia got on board June 25 and New York a month later. However, North Carolina delayed 17 months and Rhode Island nearly two years before they came in from the cold.

Notes on the Constitutional Convention:
-- Some delegates left early due to illness, frustration, business emergencies, or they returned home to complain to their legislatures.
-- Like Rhode Island, New York saw no need for a convention but sent delegates at the last minute. However, only Hamilton stayed and signed although he objected to the failure of the proposed "plan" to call for a stronger central government. Hamilton saw no need for state legislatures!
-- Thomas Jefferson was not a delegate because he was serving as emissary to France. But as a matter of protocol he received a copy of the final document before it went to the states.
