The Chicago Sun-Times is reporting that U.S. Senator Dick Durbin is leading State Senator Jim Oberweis by a margin of 47.8% to 40.5%.
Libertarian Party candidate Sharon Hansen got about 4%.
7.6% were undecided.
The margin of error is 3%.
That means Oberweis could have 43.5% and Durbin 44.8%.
Nevertheless, it is unlikely that the margin of error would end up with those results.
