A special election to fill a State Senate vacancy that was created when Senator Jon Dolan of Lake St. Louis resigned will keep the seat in Republican control. Representative Scott Rupp of Wentzville captured just under 54 percent of the votes cast in his contest with Democrat Representative Wayne Henke of Troy. The Senate district takes in parts of St. Charles and Lincoln Counties. The new make up of the 34 member Senate will have 23 Republicans and 11 Democrats.
