the Supreme Court held that a redistricting plan must be subjected to strict scrutiny if the jurisdiction used race as the "predominant factor" in determining how to draw district lines. The court defined "predominance" as meaning that the jurisdiction gave more priority to racial considerations than to traditional redistricting principles such as "compactness, contiguity, [and] respect for political subdivisions or communities defined by actual shared interests." In determining whether racial considerations predominated over traditional redistricting principles, courts may consider both direct and circumstantial evidence of the jurisdiction's intent in drawing the district lines, and irregularly-shaped districts constitute strong circumstantial evidence that the jurisdiction relied predominately on race. If a court concludes that racial considerations predominated, then a redistricting plan is considered a "racially gerrymandered" plan and must be subjected to strict scrutiny, meaning that the redistricting plan will be upheld as constitutional only if it is narrowly tailored to advance a compelling state interest. In Bush v. Vera (1996), the Supreme Court in a plurality opinion assumed that compliance with Section 2 or Section 5 of the Act constituted compelling interests, and lower courts have treated these two interests as the only compelling interests that may justify the creation of racially gerrymandered districts. In Hunt v. Cromartie (1999) and its follow-up case Easley v. Cromartie (2001), the Supreme Court approved a racially focused gerrymandering of a congressional district on the grounds that the definition was not pure racial gerrymandering but instead partisan gerrymandering, which is constitutionally permissible. With the increasing racial polarization of parties in the South in the U.S. as conservative whites move from the Democratic to the Republican Party, gerrymandering may become partisan and also achieve goals for ethnic representation. Various examples of affirmative racial gerrymandering have emerged. When the state legislature considered representation for Arizona's Native American reservations, they thought each needed their own House member, because of historic conflicts between the Hopi and Navajo nations. Since the Hopi reservation is completely surrounded by the Navajo reservation, the legislature created an unusual district configuration for the 2nd congressional district that featured a fine filament along a river course several hundred miles in length to attach the Hopi reservation to the rest of the district; the arrangement lasted until 2013. The California state legislature created a congressional district (2003–2013) that extended over a narrow coastal strip for several miles. It ensured that a common community of interest will
