Partisan Population Distribution

[Benj]

It seems like most states favor the Republicans, due to the Rural-Urban divide. Maryland comes to mind as an extremely democratic state that nonetheless favors the GOP in redistricting.

Texas has a huge Urban population but a poor layout for the GOP. Reason being that the urban Hispanic districts, despite being effective % packs, pack in fewer actual votes and leave them with heavily overpacked suburban districts and counties.

Districts are drawn by population, not voter turnout. Whether voters in one district turnout more than voters in another one is up to the voters.

Whether persons in one district are eligible to vote depends on their age and citizenship status.  Whether eligible voters vote depends in part on their age and ethnicity and income.

Agree with this. While overall population is one way to distribute electoral districts, I don't think it has any kind of moral superiority to distribution of districts by voting-eligible population. (Distributing by voting-age population is problematic, though, because it's not at all clear why age should determine distribution when age is not the only factor in eligibility.)

Distributing by actual voters voting has serious problems with how to determine turnout.
