Breaking: Former Iowa First Lady Christie Vilsack is expected to announce her intentions to run in Iowa's 4th Congressional District to take on Republican Congressman Steve King, according to Democratic sources. This shouldn't shock many people following the former first lady's travels in the state. The Vilsacks sold their home in Mt. Pleasant months ago and later left the home where they lived in Des Moines. They got a place in Ames and Vilsack has been traveling the district and raising money for the better part of this year. Vilsack has an event scheduled to announce her plans Tuesday morning at Iowa State's Memorial Union.
