not use a redistricting plan to conduct an election if the plan’s congressional districts, when considered cumulatively on a statewide basis, have been drawn with the intent or have the effect of materially favoring or disfavoring any political party. (2) Determination of effect The determination of whether a redistricting plan has the effect of materially favoring or disfavoring a political party shall be based on an evaluation of the totality of circumstances which, at a minimum, shall involve consideration of each of the following factors: (A) Computer modeling based on relevant statewide general elections for Federal office held over the 8 years preceding the adoption of the redistricting plan setting forth the probable electoral outcomes for the plan under a range of reasonably foreseeable conditions. (B) An analysis of whether the redistricting plan is statistically likely to result in partisan advantage or disadvantage on a statewide basis, the degree of any such advantage or disadvantage, and whether such advantage or disadvantage is likely to be present under a range of reasonably foreseeable electoral conditions. (C) A comparison of the modeled electoral outcomes for the redistricting plan to the modeled electoral outcomes for alternative plans that demonstrably comply with the requirements of paragraphs (1) through (6) of subsection (a) in order to determine whether reasonable alternatives exist that would result in materially lower levels of partisan advantage or disadvantage on a statewide basis. For purposes of this subparagraph, alternative plans considered may include both actual plans proposed during the redistricting process and other plans prepared for purposes of comparison. (D) Any other relevant information, including how broad support for the redistricting plan was among members of the entity responsible for developing and adopting the plan and whether the processes leading to the development and adoption of the plan were transparent and equally open to all members of the entity and to the
