On her way to a convincing victory, Rep. Tammy Duckworth won only 17 of Illinois' 102 counties, mirroring the urban-rural divide seen across the country on Election Day. While Duckworth's percentage-point winning margins weren't nearly as wide as incumbent Sen. Mark Kirk's, the counties Duckworth won had much larger margins in terms of total votes.
Kirk won only three counties by more than 10,000 votes, while Duckworth won five, including a massive 900,000-vote margin in Cook County, 23,350 in Will County and 14,296 in Lake County. Kirk won 14 counties by more than 40 percentage points, but that only netted him 62,245 more votes.
