WASHINGTON (CNN) – Christie Vilsack, the wife of former Iowa Gov. Tom Vilsack, announced Monday that she will not challenge Republican Charles Grassley for his Senate seat in 2010.
"I am flattered and humbled by the requests from Democrats, Independents and even some Republicans to consider running," Vilsack said in a statement released Monday. "My careful consideration of the opportunity to represent Iowa in the Senate was done with great respect for those who came to me and the office itself."
Vilsack also said that she will continue to be active in Democratic politics in Iowa "and across the state in issues that affect the quality of life for all Iowans."
"While I will not be a candidate for office in 2010, never doubt I am committed to a life of service and to Iowa," she added.
Recent comments by Vilsack had led some political observers to believe that the she might mount a challenge to Grassley, who is up for re-election next year.
In addition to being Iowa's former governor, Vilsack's husband is now President Obama's Secretary of Agriculture.
