Two factors were potent in securing the final success of the new plan. One was the provision in the last clause by which the new frame could be amended easily. The unanimity which the Articles required in order to correct a mistake had taught a valuable lesson. Three-fourths was to be the maximum requirement hereafter. It is interesting to note that a unanimous vote has never been obtained on any amendment thus far made to the Constitution. The other favourable circumstance was the tacit understanding that Washington would consent to serve as the first President, guaranteeing the perpetuity of the Republic by his past record. His fidelity had been tested at the close of the Revolutionary War, when a devoted army might have made him a Julius Caesar or an Oliver Cromwell in the chaotic condition of affairs. That he had returned to his Virginia farm to become an active citizen was an assurance that he could now be trusted with the vast powers conferred on the chief executive under the new plan. The State conventions were not slow to take advantage of the privilege of proposing amendments, and these the promoters were too wise to resist. Proposals to make amendments were non-committal and harmless where the motto was "Anything to get the new plan in operation." Massachusetts wished nine additions made, South Carolina four, Virginia twenty, New Hampshire twelve, New York thirty-two, and North Carolina twenty-six. Of the 103 propositions submitted to the consideration of Congress by the conventions, many were duplicates. Only ten were destined to survive. At the time, they served as a machine of the gods to avert the dangerous proposition that another convention be held to draw up a second constitution embracing the desired changes.
