Albany County was governed by a board of supervisors until 1968. The board consisted of the town supervisors of each town in the county, as well as county supervisors elected from the wards of each city in the county. In the later years of its existence, the board used a system of weighted voting to comply with recently enacted federal and state proportional representation requirements. On January 1, 1976, Albany County government was changed by a new charter establishing a county executive elected at-large, in addition to the 39-seat county legislature. Each of the 39 legislators are elected from single-member districts. As of 2015, the county council has 29 Democrats, 9 Republicans and 1 Conservative, who caucuses with the Republicans.
