Instead, they're discussing who's the least trustworthy.
Republican U.S. Rep. Mark Kirk says Democrat Alexi Giannoulias is a "mob banker." His allies compare Giannoulias to Tony Soprano and criticize him for wrongly claiming to still head a charity that's actually defunct.
Meanwhile, Giannoulias argues Kirk has a problem with the truth. His campaign highlights every new development related to Kirk exaggerating his military service.
Illinois finds itself in an odd parallel universe in this midterm election as the rest of the country watches an ideological clash between the parties over the size of government and the best answers for the recession, with the insurgent tea party movement fanning the debate.
Illinois' candidates, while competing for President Barack Obama's old seat, are talking mostly about each other. The disparity is causing confusion among some voters.
"I want to hear what they propose will help Illinois and get the state out of the mess it's in," said Wayne "Ren" Sirles, 68, a peach and apple grower in rural southern Illinois, where both candidates have campaigned. "Come and tell me what you're proposing."
Bob Biehl, a corn and soybean grower near Belleville in southwestern Illinois, said he also is wondering about the precarious economy.
"I would want to hear about their positives and what they can do," Biehl said. "This country's in a world of hurt as far as I'm concerned."
The exchange of insults rather than ideas speaks to certain political conditions prevailing in the race, and it's not clear if and when the subject will change.
As a Republican competing in a Democratic-leaning state with many moderate independent voters, Kirk may be less eager to heighten the philosophical differences being pressed by his GOP counterparts in more conservative places, such as sharp cutbacks in government and tough new restrictions on immigrants.
And recent political scandals involving Illinois Democrats and the corruption trial of ousted Gov. Rod Blagojevich make ethics a ripe issue. Trashing one's opponent "is a distasteful but long-standing tradition in American politics," said DePaul University political science professor Michael Mezey.
With his business record and character under attack, Democrat Giannoulias clearly relishes responding in kind when the opportunity arises.
Campaign officials say that between the attacks and counterattacks, Giannoulias is still finding time to talk about the issues in the state. "When we go out there, when we're talking to voters, we're not talking about the headlines of the newspaper. Alexi is talking about jobs and the economy and having that discussion," Giannoulias spokesman Matt McGrath said. When he talks about issues, Giannoulias tries to link Kirk to the GOP establishment.
Kirk, too, has tried to focus on "low tax, pro-growth job creation policies," said Kirk spokeswoman Kirsten Kukowski.
Who is gaining the most from the mutual abuse isn't clear. The new stain on Kirk over his misrepresentation of his military record may help reduce the impact of Giannoulias' past problems, including his family's failed bank.
The campaigns went negative from the get-go and have grown increasingly so with the recent disclosure that Kirk embellished some accomplishments during his 21 years in the Naval Reserves.
