On tonight's edition of Chicago Tonight: The Week in Review -- Midterm elections are fast approaching and cliffhangers remain in key races. We recap this week's news in the Governor's race, as Pat Quinn tries to close in on Bill Brady. We recount the heated debate between Senate candidates Mark Kirk and Alexi Giannoulias as polling continues to show them neck-and-neck. We also take a look at key House races, and what early voter turnout indicates about how the races will be decided. Cook County Sheriff Tom Dart is not running for Mayor -- we analyze what may have influenced his decision and how it will impact that race. In sports, a full slate of analysis on the Bulls, the Bears, and the Hawks -- and a look at the tragedy of a student's death in the wind storm during football practice at Notre Dame.
