According to this story, Illinois elections officials have made absentee ballots available, but are asking voters not to use them, because the final ballot may have a different set of candidates.  First, as the story mentions, the Constitution Party statewide slate may be added to the ballot if the party wins in court.  The hearing is Friday, September 24.

Also, in one State Senate race, the Illinois Supreme Court will soon decide whether the Republican nominee, Steve Rauschenberger, should be removed from the ballot.  See this story.  The hearing is Wednesday, September 22.  Democrats want to remove Rauschenberger from the ballot because he voted in a Democratic primary for local office in 2009.  The story’s use of the term “open primary” doesn’t mean a “top-two” system.  It is the Illinois term for the type of open primary in which the voter need not choose a primary ballot in public, but rather decides in the secrecy of the voting booth which party primary to choose.  Illinois already has an open primary.
