2012 United States House of Representatives elections in Missouri

A new congressional map was passed by the Missouri General Assembly on April 27, 2011.^[2] The map was vetoed by Democratic Governor Jay Nixon on April 30,^[3] but Nixon's veto was overridden by the General Assembly on May 4, making the plan law.^[4] The map effectively eradicated the former 3rd district, which had been represented by Democrat Russ Carnahan since 2005, splitting it between the districts represented by Republicans Blaine Luetkemeyer and Todd Akin and Democrat William Lacy Clay, Jr. The bulk of the old 9th district became the new 3rd district.^[2]

3rd District Congressman Russ Carnahan briefly mulled over a run in this district, though the district was more Republican than his previous district, and Carnahan did not live in the district.^[16] A poll commissioned by Carnahan showed Carnahan being competitive with Ann Wagner and Ed Martin.^[17] The Democratic Congressional Campaign Committee had preferred that Carnahan run in the district, and considered him a member of the Frontline program for vulnerable members.^[18] Ultimately, Carnahan would run unsuccessfully for the 1st district.

Whitfield requested a recount, as the race was separated by less than 1%. By September 13, 2012 the recount was completed and Koenen was declared the winner.
