Former Madison County Judge Ann Callis picked up the Democratic nomination in Illinois’ 13th District Tuesday night and will now face a top target of national Democrats, freshman GOP Rep. Rodney Davis.  

Callis defeated physics professor George Gollin 59 percent to 28 percent, with 56 percent of precincts reporting, according to The Associated Press. A third candidate, David Green, garnered 13 percent.  

Davis defeated former Miss America Erika Harold 57 percent to 38 percent, with 65 percent of precincts reporting.  

The Democratic Congressional Campaign Committee backed Callis in the primary, and party operatives say she is the best candidate to defeat Davis in this swing district. President Barack Obama and GOP presidential nominee Mitt Romney each received 49 percent of the district’s vote in 2012.  

On the GOP side, Harold’s candidacy drew national attention last summer when she announced a primary challenge to Davis, but she never emerged as a serious threat to Davis’ political future. Harold failed to raise substantial funds and had trouble coalescing Republicans support.  

The contest between Davis and Callis will likely be one of the marquee House races in 2014, with millions from outside groups likely to be dumped onto the airwaves. Illinois’ 13th District is rated a Tilt Republican contest by Rothenberg Political Report/Roll Call.  

On the top of the ticket, dairy magnate Jim Oberweis captured the GOP nomination for Senate. Oberweis defeated Army veteran Doug Truax 55 percent to 45 percent, with 54 percent of precincts reporting, according to the Associated Press .  

Oberweis, who has run two failed Senate bids, two failed House bids and a failed gubernatorial bid since 2002, will take on Democratic Sen. Dick Durbin in November. The race is rated Safe Democratic by Rothenberg Political Report/Roll Call.
