Cayuga County, New York, elects 15 members to its County Legislature, on a partisan basis. The 15 districts are not similar to each other in population. Instead, the county has a system in which each member’s vote in the Legislature depends on how many constituents he or she has. The legislator with the most constituents casts 81 votes (called “points”) each time he votes; by comparison, the legislator with the fewest constituents casts 47 points.
Democrats in the Cayuga County legislature are suggesting that this system be ended, and that the districts be redrawn so that each district is approximately equal in population. See this story.
