Why was Hamilton the only signer from NY?

Alexander Hamilton was the only signer of the U.S. Constitution from New York because he was a staunch advocate for the document and played a pivotal role in its drafting and ratification. Many of the other delegates from New York were either absent or opposed to the Constitution, particularly due to concerns about federal power versus states' rights. Hamilton's strong support and persuasive arguments were crucial in securing New York's eventual ratification of the Constitution.
