Impact of redistricting
- See also: Redistricting in Illinois
With the 2011 redistricting, Illinois lost 1 of its current 19 House seats because the state's population failed to grow as fast as in other states. Illinois has had 11 Republican congressmen and 8 Democrats since the November 2010 election. The new map, designed by the dominant Democrats, could flip that advantage to as many as 12 Democrats and only six Republicans.
