The SCOTUS heard oral arguments in two redistricting cases. The transcripts of the arguments are here:
MathismanderThis is whether Republican districts can be underpopulated if there is some other pretext, and they keep the deviation under 10%.
There are a lot of parallels to the Virginia congressional case, because Arizona is arguing that the reason they discriminated was to get the executive branch of the federal government to approve their plan. Both Arizona and Virginia had their plans approved by the USDOJ.
Incidentally, when the independent redistricting commission was approved, it was claimed that the deviation for legislative districts would be similar to that for Congress.
Does one man, one vote mean?This is the Texas case whether districts used to elect legislators must have equal numbers of electors.
The arguments are pretty interesting since Texas was making a different argument than the United States.
