The redrawn 13th district will likely be a new home for Rep. John Shimkus (R). However, Democrats crafted the new region to include more competitive territory. As a result, Shimkus could have a more serious challenge in 2012 than heís had in previous cycles.
Rep. Jerry Costello (D), the dean of the delegation and point man for redistricting, did not see too much change is his 12th district in southwestern Illinois, which still includes the Democratic-heavy East St. Louis. However, if Costello retires sometime in the next decade, this could potentially be a competitive seat.
Similarly, Rep. Timothy Johnsonís (R) district has shifted south and now includes a much larger geographical area. However, its composition as a heavily Republican district did not change.
In other redistricting news, the Nebraska Legislature passed a redistricting map that Gov. Dave Heineman (R) signed into law Thursday. The new map makes minor tweaks to the stateís Congressional districts, but it does make the Omaha-based 2nd district less competitive by moving into it some heavily suburban GOP counties.
