State Rep. Tim Schmitz easily fought off a challenge from a Democratic newcomer in the 49th District, according to unofficial results.
With all 90 precincts counted, Schmitz had about 64 percent of the vote compared to 34 percent for Jennifer Barconi.
Schmitz said he won because after 11 years in Springfield, voters know and trust him.
"People get to know you, and they know what you stand for," Schmitz said. "That doesn't happen overnight."
Schmitz said he will focus on putting more teeth into campaign finance reform when he is sworn in again.
Barconi said she simply couldn't match her opponent's name recognition.
"I'm the new kid on the block," Barconi said. "It's hard being grass roots and true to who you are."
Barconi said she plans to stay involved.
"In 2012, I'll be running again," she said. "I'm not giving up. I'm a fighter, and I'm very competitive."
The race in the state's 49th House District pitted a veteran Republican lawmaker against a relatively unknown Democrat.
Schmitz, a Batavia firefighter who has served in the House since 1999, pledged to pursue legislation that would make Illinois more attractive to potential employers. Barconi, an Air Force veteran and business owner from South Elgin, said she would focus her efforts on marketing the state's advantages to businesses looking to move or expand.
The candidates also had different ideas on how to approach the state's ailing budget.
Schmitz, who believes Illinois should go on a "strict diet," joined the call for zero-based budgeting and a forensic audit of the state's budget ideas supported by many Republicans and some Democrats.
Barconi expressed support for a package of cuts proposed by 10 Democratic state lawmakers.
The one weapon both candidates agreed they would not support to balance the state's budget: a tax increase.
The 49th District includes a good portion of the Fox Valley between Batavia and Carpentersville.
