On June 24, Congressmember John Tanner (D-Tennessee) introduced HR 3025, which sets up federal standards for states when they draw U.S. House districts. Here is the 21-page bill. It says that each state must have an Independent State Commission to draw these districts.
The Commissioners would be chosen by the leaders of the two political parties that have the most seats in each state’s legislative bodies (i.e., Democratic and Republican legislative leaders, except in states with non-partisan legislatures, although Nebraska is the only such state). The Commission’s plans must not take into consideration the voting history of a district (unless a separate state law requires it). The plans must not taken into account the partisan registration of any areas, nor the location of residence of incumbent members of the U.S. House.
