All 150 members of the New York State Assembly and all 63 seats of the New York State Senate were up for election. There are no term limited members as New York does not have term limits for positions at the state level. Members of the Assembly and the State Senate serve two year terms. The State Senate was heavily contested as the Democrats and Republicans both had 31 seats with the Republicans only controlling the Senate through a coalition deal with Democratic Senator Simcha Felder and the Independent Democratic Conference. The 2016 United States presidential election also occurred on the same date as the general election.
