Each Wisconsin State Senate district is composed of three Wisconsin State Assembly districts. The 27th Senate district comprises the 79th, 80th, and 81st Assembly districts. The current representatives of those districts are:

The area of the district in Columbia County, however, falls within Wisconsin's 6th congressional district, which is represented by U.S. Representative Glenn Grothman.[6]
