Ethan Hastert, son of the former House Speaker, has lost his bid to reclaim that seat for the family. State Sen. Randy Hultgren (R) will now face off against Rep. Bill Foster (D) in the 14th Congressional District.

The hottest race of the night continues to be the Republican primary for governor, where Kirk Dillard -- who famously appeared in a TV ad for Barack Obama's presidential campaign -- is clinging to the slimmest of leads over state Sen. Bill Brady. In the Democratic race, Gov. Pat Quinn (D) is also holding on to a small lead.

Results as of 11:42 pm ET:
IL GOV (D): Quinn 50.3% -- Hynes 49.7%
IL GOV (R): Dillard 20.2% -- Brady 20.1% -- McKenna 19.2% -- Ryan 17.1% -- Andrzejewski 14.6%
IL 10 (D): Seals 48.0% -- Hamos 46.6%
IL 10 (R): Dold 38.6% -- Coulson 30.6%
IL 14 (R): Hultgren 54.7% -- Hastert 45.3%
IL SEN (D): Giannoulias 39.0% -- Hoffman 34.0% -- Jackson 19.4%
