Republican David Olsen, who this summer was appointed to the state's 81st House District seat, won his own term Tuesday.
Olsen defeated Democratic challenger Greg Hose by tallying 27,818 votes -- or 54 percent -- to Hose's 24,145 votes -- or 46 percent -- according to unofficial results with all 108 precincts in DuPage and Will counties reporting.
Olsen, 28, of Downers Grove, was appointed July 30 to the seat representing all or parts of Downers Grove, Darien, Lisle, Bolingbrook, Naperville, Westmont and Woodridge after the resignation of former state Rep. Ron Sandack.
Olsen called it "a great honor to win the election and to clearly have the confidence of the voters."
Now he says he's ready to build consensus and address state finances.
Olsen's rise to an elected term in the seat comes after the former Downers Grove village commissioner was appointed early this year to the contentious College of DuPage board and to the 81st District position.
