About 48 percent of registered voters in McHenry County cast their ballots Tuesday, according to unofficial results Tuesday evening. Contested races for Illinois governor, attorney general, secretary of state, comptroller, treasurer, U.S. House seats, Illinois House and Senate seats, McHenry County Board seats and county clerk were on the ballot. Rain earlier in the day didn't seem to hinder McHenry County residents, who formed lines outside several polling locations before voting opened Tuesday morning.
