Under the provisions of the New York Constitution of 1777, the State Senators were elected on general tickets in the senatorial districts, and were then divided into four classes.
Six senators each drew lots for a term of 1, 2, 3 or 4 years and, beginning at the election in April 1778, every year six Senate seats came up for election to a four-year term.
Assemblymen were elected countywide on general tickets to a one-year term, the whole assembly being renewed annually.
Pierre Van Cortlandt were re-elected to a fourth term.
Senators Lewis Morris (Southern D.), John Williams (Eastern D.) and Abraham Yates Jr. (Western D.) were re-elected; and John Hathorn (Middle D.), Peter Schuyler (Western D.) and Assemblyman John Vanderbilt (Southern D.), were elected to the Senate.
