The Bronx and Manhattan lie on the eastern edge of the Newark Basin, a block of the Earth's crust which sank downward during
1993 New York City mayoral election in Staten Island; a referendum on Staten Island's secession from New York City was placed on the ballot that year by Governor Mario Cuomo and the New York State Legislature. Dinkins defeated Giuliani handily in Manhattan, Brooklyn, and the Bronx, but Giuliani's margin in the other two boroughs was large enough to win the election. Giuliani won by a margin of 53,367 votes. He became the first Republican elected Mayor of New York City since John Lindsay in 1965.
