Incumbent: Heading into the election the incumbent was Ed Pastor (D), who was first elected in 1991. As a result of redistricting, Pastor ran for election in the 7th congressional district.[3]

This was the first election using new district maps based on 2010 Census data. The 4th district covers the entire western portion of Arizona. Mohave, Yavapai, Gila, Pinal, La Paz, and Yuma counties are included in the new district boundaries.[4]

Impact of redistricting

See also: Redistricting in Arizona

The 3rd district was re-drawn after the 2010 Census. The new district is composed of the following percentages of voters of the old congressional districts.[9][10]

Registration statistics

As of October 22, 2012, District 4 had the following partisan registration breakdown according to the Arizona Secretary of State:

Arizona Congressional District 4[11]
Congressional District District Total Democrats Republicans Other & Unaffiliated Advantage Party Advantage Change in Advantage from 2010
District 4 366,297 81,646 153,708 131,643 Republican 88.26% 240.17%
"Party advantage" is the percentage gap between the two major parties in registered voters. "Change in advantage" is the spread in difference of party advantage between 2010 and 2012 based on the congressional district number only.

In 2012, FairVote did a study on partisanship in the congressional districts, giving each a percentage ranking (D/R) based on the new 2012 maps and comparing that to the old 2010 maps. Arizona's 4th District became more Republican because of redistricting.[12]

  • 2012: 31D / 69R
  • 2010: 41D / 59R
