SPRINGFIELD - The three candidates vying to succeed U.S. Rep. Ray LaHood used every opportunity during a debate Monday to distinguish themselves from one another, especially when it comes to experience.

Republican Aaron Schock of Peoria tried to stress his experience in government so far, despite his age of 27.

"I'm the only candidate that's held elected office," said Schock, now serving as a state lawmaker from Peoria.

But Democrat Colleen Callahan of Kickapoo and Green Party candidate Sheldon Schafer of Peoria argued voters wanted someone without a political background.

Callahan appeared to take direct aim at Schock.

"This is not a time to build a resumé," she said.

The debate visited issues that have come up in the campaign's past months, including Callahan's call for the United States to reinstitute a draft in some form.

She has proposed that every young person of a certain age be required to serve to the country in the military or otherwise.

"It is the fairest way to rebuild our military," Callahan said.

Schock shot back that a military staffed with unwilling soldiers could have "catastrophic" results. He also wondered what would happen if a large segment of the population was volunteering and not working.

"What would be the impact on the economy?" he said.

Schafer, who served in the Peace Corps, said he valued the idea of service but wondered if it was practical to draft every person of a certain age into action.

"It's certainly problematic," he said.

The 18th Congressional District includes Logan County, parts of Decatur and Macon County, and parts of Woodford and Tazewell counties.

Much of the last month of the campaign likely could focus on economic issues, as many voters see that as the nation's top concern. Callahan and Schock reiterated Monday that they would have supported the $700 billion bailout plan that was approved by Congress last week.
