George Gollin, physics professor at the University of Illinois at Urbana-Champaign, is in the final two weeks of the primary campaign for the 13th Congressional District (though early voting started yesterday). There are two other candidates in the Democratic primary, and the current Representative, Rodney Davis, is expected to win the three-candidate Republican primary.
Gollin announced last summer. He has some policy experience, having worked hard to break up some diploma mills (which probably explains some of the stringent objections to Gollin you might stumble across online). It led to him trying to get diploma mill legislation passed in Congress, so he has already been disillusioned. While he does not have the support of the Democratic Congressional Campaign Committee (DCCC), he did receive the endorsement of the Chicago Tribune (H/T ScienceInsider). I have not been able to find any polling information on the Democratic primary, but funding reports indicate that Gollin has about half as much cash on hand as the DCCC-supported candidate.
Good luck to George.
