The following bit is from Ballot Access News:
On February 28, the Illinois voter who had challenged three minor party or independent candidates’ petitions (in the special election to fill the U.S. House vacancy in the 2nd district), withdrew her challenges. Therefore the April ballot will include the nominees of the Democratic, Republican, and Green Parties, along with three independent candidates. The Green nominee is LeAlan Jones. The three independents are Marcus Lewis (who never was challenged and who has been on the ballot all along), Elizabeth Pahlke, and Curtiss Bey.
Now that the major party primaries for this election are over with, the Illinois media is reporting that the Republican nominee, Paul McKinley, was convicted of burglary long ago and served time in prison. See this story (http://www.chicagotribune.com/news/local/ct-met-2nd-district-republican-nominee-20130228,0,3550456.story).
The Democratic nominee is Robin Kelly.
Side note from poster: The Socialist Workers Party candidate, John Hawkins, is running as a write-in candidate.
