The 2010 New York state elections took place on November 2, 2010. These included elections for both Senate seats and a gubernatorial election.
Due to the special election for US Senate, all of New York's six statewide offices were up for popular election on the same date. At the same time, all 29 members from New York of the U.S. House of Representatives, all 212 members of the New York State legislature, and many other local officers were elected.
The Democratic Party swept all of the statewide races, but Republicans made net gains of six seats in the House of Representatives, nine seats in the state Assembly (breaking the veto-proof Democratic supermajority in that chamber) and two seats in the New York State Senate, the last of which delivered the Senate chamber back to the Republican Party.
Democratic Senator Charles Schumer won reelection against Jay Townsend, his Republican opponent.
Democratic Senator Hillary Clinton resigned to become United States Secretary of State in the Obama Administration. Kirsten Gillibrand had been appointed to the seat by Governor David Paterson in 2009, and won the general election on November 2, 2010, to hold the seat for the remainder of its term, against Republican Joseph J. DioGuardi.
29th district seat was vacated by Eric Massa, who resigned March 8. Under the authority of Article I in the U.S. constitution and provisions in New York state law, Governor David Paterson was supposed to call a special election in spring 2010 to fill the seat, but waited until September to call the election concurrent with the general election. The seat remained vacant from March 8, 2010 until new Congressman Tom Reed was sworn in, in November 2010.Two concurrent elections were held, one to fill the remainder of Massa's term (November to January) and one to fill the seat in the subsequent Congress. Both elections had the same candidates on the ballot, Democrat Matthew Zeller and Republican Tom Reed. Reed prevailed in both elections.
