The 2012 United States House of Representatives elections in Iowa were held on Tuesday, November 6, 2012 to elect the state's four U.S. Representatives. The elections coincided with the elections of other federal and state offices, including a quadrennial presidential election. Primary elections were held on June 5, 2012.[1]
Bruce Braley, a Democrat the incumbent representative from the 1st district in northeastern Iowa since 2007, ran in the new 1st district. Fellow incumbent Dave Loebsack, who lived within the boundaries of the new 1st district in Linn County, but who had represented southeastern Iowa's 2nd district since 2007, moved to Johnson County and ran in the new 2nd district.[4] The 1st district has become more favorable to Democrats with the inclusion of Linn County and its loss of Scott County.[5] Braley won the Democratic nomination unopposed.[6]
None of Iowa's current members of Congress resided in the newly-drawn 2nd district; however, Democrat Dave Loebsack moved from Linn County to Johnson County in order to avoid a primary against Bruce Braley and continue representing southeastern Iowa.[4] The 2nd district became slightly more favorable to Republicans as a result of the inclusion of Scott County, but retains Democratic-leaning Johnson County.[5]
Leonard Boswell, a Democrat who represented the 3rd district in central Iowa since 1997, and Tom Latham, a Republican who represented the 4th district in northern and central Iowa since 1995, both ran in the new 3rd district.[13] Latham, who lived in the new 4th district, moved south to avoid facing fellow Republican Steve King in a primary.[14] Approximately half of the new 3rd district was represented by Boswell, whereas the new 3rd district contains more than 20 percent of the area currently represented by Latham.
Steve King, a Republican represented western Iowa's 5th district since 2003, ran in the new 4th district. Christie Vilsack, the former First Lady of Iowa, was the Democratic nominee against King. Brady Olson also ran in the Liberty party against both King and Vilsack.[16] The new 4th district comprises mostly territory which King represented and which tends to vote for Republican candidates.
