Keep in mind that there is no deadline in IL for the congressional redistricting other than what is needed to meet federal law. Talk about alternative data sets are most important for legislative redistricting which has a Jun 30 deadline before a bipartisan back-up commission is formed to draw the maps. Congressional maps can be drawn and passed in late Aug using real 2020 Census data in the "legacy" format, and it won't affect the primary date or Dem control over the process.
I thought that the Illinois Supreme Court had construed the state constitution to require strict equality among legislative districts.
What data did they use? The legislative redistricting sites showed maps but no data?
The house districts in Chicago are horrible. Can an equal protection case be made for extending districts out for 40 miles in order to pick up population but retain effective control in Chicago?
