Cook County Chief Administrative Officer Robin Kelly won the special election to replace former Rep. Jesse L. Jackson Jr. on Tuesday.

Kelly, a Democrat, defeated Republican Paul McKinley, 89 percent to 6.6 percent, with 19.8 percent of precincts reporting, according to The Associated Press.

Her victory came as no surprise. The 2nd District is heavily Democratic and Kelly had minimal opposition in the general election. McKinley is a convicted felon, according to numerous news outlets.

Kelly's real political test came in the February primary, which she also won by a landslide. She defeated a large field of candidates, including former Democratic Rep. Debbie Halvorson.

New York Mayor Michael Bloomberg took partial credit for Kelly's win after his super PAC spent $2 million on ads boosting her. Kelly's support for gun control legislation prompted the super PAC's support.
