New York City: the 51st State was the platform of the Norman Mailer–Jimmy Breslin candidacy in the 1969 New York City Democratic Mayoral Primary election. Mailer, a novelist, journalist, and filmmaker, and Breslin, an author and at the time a New York City newspaper columnist, proposed that the five New York City boroughs should secede from New York State, and become the 51st state of the U.S.

James Earle Breslin was an American journalist and author. Until the time of his death, he wrote a column for the New York Daily News Sunday edition. He wrote numerous novels, and columns of his appeared regularly in various newspapers in his hometown of New York City. He served as a regular columnist for the Long Island newspaper Newsday until his retirement on November 2, 2004, though he still published occasional pieces for the paper until his death.
