Arizona's 2nd congressional district is a congressional district located in the U.S. state of Arizona. For election purposes, it is now located in the northeast corner of the state. For representational purposes until January 2023, it was located in the southeastern corner of the state and includes roughly two-thirds of Tucson. District history When Arizona was divided into congressional districts for the first time after the 1950 Census, the 2nd district comprised the entire state outside of the Phoenix area. Arizona gained a third district after the 1960 Census, and the 2nd was cut back to roughly the southern third of the state, stretching border-to-border from New Mexico to California. It ran along the entire length of the border with Mexico. By far the district's largest city was Tucson. The next largest city was Yuma, in the far west. After a mid-decade redistricting in 1967, the district was pushed slightly to the north, picking up a portion of southern Phoenix. This configuration remained largely unchanged until the 1980 Census, when much of eastern Tucson was drawn into the new 5th district. The 2nd district remained based in southern Arizona until the 2000 Census, when Arizona picked up two districts. At that time, the old 2nd district essentially became the new 7th district, while most of the old 3rd district became the new 2nd district. Located in the northwestern corner of the state, it stretched into the western suburbs of Phoenix, known as the West Valley. It consisted of all of Peoria (within the exception of the portion of that city within Yavapai County) and Surprise, most of Glendale and much of western Phoenix in Maricopa County, all of Mohave County, and the Hopi Nation in Navajo and Coconino counties. The size and diversity of the 2nd district (it included nearly all of the northwestern portion of the state) made it appear rural on a map. However, over 90 percent of its population lived in the strongly conservative West Valley, historically a fairly safe Republican area. The odd shape of the district was indicative of the use of gerrymandering in its construction. The unusual division was not, however, drawn to favor politicians, but was due to historic tensions between the Hopi and the Navajo Native American tribes. Since tribal boundary disputes are a federal matter, it was long believed inappropriate to include both tribes' reservations in the same congressional district. However,
