Former state representative Robin Kelly (D) easily won a special election in Illinois' 2nd congressional district Tuesday, capturing the seat once held by embattled Democrat Jesse Jackson Jr.

With 20 percent of precincts reporting, the Associated Press called the race for Kelly, who led Republican nominee Paul McKinley 89 percent to 7 percent.

Kelly's fate was essentially sealed when she won the February 26 Democratic primary. With a boost from gun control advocates, including New York City Mayor Michael Bloomberg (I), Kelly cruised to victory in a crowded Democratic race, all but ensuring a trip to Congress. The overwhelmingly Democratic district includes Chicago’s South Side and extends into the suburbs south of the city.
