Redistricting

Due to population gains reflected in the 2010 United States census, Arizona's congressional delegation increased from eight members to nine in 2012. In accordance with the Arizona Constitution, the Arizona Independent Redistricting Commission produced new congressional district maps for use in the 2012 and subsequent elections. In October 2011, the commission released a draft map and by November 5 that year had completed a round of public hearings for input on the draft map. The map became final after being cleared for compliance with the Voting Rights Act by the United States Department of Justice, and established the official district boundaries for the 2012 elections.

On November 1, 2011, Arizona Governor Jan Brewer, with the approval of the Arizona Senate, removed Colleen Mathis, the commission's chair, charging Mathis was guilty of "failure to apply the Arizona Constitution's redistricting provisions in an honest, independent and impartial fashion." On November 17, the Arizona Supreme Court overturned Brewer's decision and reinstated Mathis. On November 21, Brewer asked the Supreme Court to reconsider its decision and to temporarily reverse Mathis' reinstatement. The Supreme Court refused. The map was pre-cleared by the U.S. Department of Justice on April 9, 2012, and was in effect for the 2012 elections.

District 1

Based upon the new map, the 1st district is slightly friendlier to Democrats than its predecessor. Incumbent Republican Paul Gosar, first elected in 2010, ran for election in the more conservative 4th district.

District 2

After redistricting, most of the 2nd district was composed of land previously located in the 8th district and was thus more favorable to Democrats. Democrat Gabby Giffords, who had represented the 8th district since 2007, was seriously wounded in a mass shooting in January 2011 and resigned her congressional seat in January 2012. A special election was held in June 2012 under the boundaries of the then current 8th district, with a primary election held in April 2012; in November 2012, another election took place under the new boundaries of the 2nd district, with a primary scheduled for August 2012.
