What arguments did Alexander Hamilton do to support their claim

Alexander Hamilton was the force behind the project, and was responsible for recruiting James Madison and John Jay to write with him as Publius. Two others were considered, Gouverneur Morris and William Duer. Morris rejected the offer, and Hamilton didn't like Duer's work. Even still, Duer managed to publish three articles in defense of the Constitution under the name Philo-Publius, or "Friend of Publius."
