Republican Representative Kenneth Keating defeated Democrat Frank Hogan to succeed Ives. As of 2020, this is the last time the Class I New York senate seat was won by a Republican.
The Liberal Party initially chose Thomas K. Finletter as its nominee for Senate, but after Finletter lost the Democratic nomination to Frank Hogan, Finletter withdrew and the party endorsed Hogan instead.
