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.[10] Illinois has had 11 Republican congressmen and 8 Democrats since the November 2010 election.[10] The new map, designed by the dominant Democrats, could flip that advantage to as many as 12 Democrats and only six Republicans.[10]

District history


On November 2, 2010, Jerry F. Costello won re-election to the United States House of Representatives. He defeated Teri Newman (R) and Rodger Jennings (G) in the general election.[11]
