In October 2009, Vilsack told
WHO-DT she was considering a possible run against Republican incumbent U.S. senator
Chuck Grassley in 2010. A
Research 2000 poll for the website
Daily Kos, conducted just days after the interview, showed that Grassley led Vilsack 51 to 40 percent in a hypothetical matchup, placing her in a statistical tie with the declared Democratic party candidates
Roxanne Conlin and
Bob Krause. She ultimately decided not to run. In April 2011, Vilsack formed an exploratory committee to prepare for a potential
campaign for Congress in Iowa's 4th District. She made her official announcement to run on July 19. On November 6, 2012, she was defeated by five-term Republican incumbent
Steve King by just over 30,000 votes. Vilsack considered running against King again
in 2014 but took a job with the
United States Agency for International Development as the Senior Advisor on International Education instead. ==Electoral history==
