States grapple with compressed redistricting timelines

A lawsuit filed this week over Illinois' new legislative district lines is a preview of what's sure to be a litigious and tense second half of the year for mapmakers.

While Illinois has made more progress than most states, the redistricting process in the Prairie State is far from over. Full census data has not yet been released due to delays caused by the COVID-19 pandemic. As a result, many states are facing impossible redistricting deadlines — some of them constitutionally mandated. If adjustments aren't made soon, courts will have to step in and draw temporary maps for upcoming elections.

Late last week, Gov. J.B. Pritzker signed legislation to establish new lines for the legislative districts in Illinois, a process the state Constitution requires to be completed by the end of this month. Because Democrats have a 73-45 majority in the House and a 41-18 majority in the Senate, they were able to quickly draw districts and get Pritzker's approval without any input from Republicans.

A few days after the new maps were finalized, the state's top Republican officials, House Minority Leader Jim Durkin and Senate Minority Leader Dan McConchie, filed a federal lawsuit. They argue the redistricting plan approved by Democrats was inaccurate, "arbitrary" and discriminatory toward minority voters.

By forgoing the official Census Bureau counts in favor of population estimates, "the Plan ensures that historically undercounted minority communities will continue to be underrepresented and lose their right to an equal vote in the legislature," the lawsuit states.

The GOP leaders want a judge to declare the redistricting plan unconstitutional and to require the Legislature to establish a bipartisan commission to draw new maps.

Redistricting has historically been a heavily litigated issue due to partisan disputes like this. But there will likely be even more challenges this time around thanks to the Supreme Court's recent landmark decision. In 2019, the five conservative justices ruled that determining whether there is a constitutional limit to partisan gerrymandering fell outside the purview of federal judges. As a result, many election maps are expected to be battled out in state courts this year.

While Illinois opted to use the population estimates already available to draw its legislative maps, most states will have to wait until more detailed data is released later this year. A delayed start could conflict with statutory deadlines set by state constitutions.

The Brennan Center for Justice, a liberal public policy institute at New York University Law School, released a report in April analyzing how census delays could impact states' redistricting plans. The Princeton Gerrymandering Project also created a tool to track how the delays are affecting states and where urgent intervention is needed most.

Hawaii and Michigan, two states with redistricting commissions, are among the most severe cases identified by both the Brennan Center and the Princeton Gerrymandering Project because they have fixed dates for redistricting.

Hawaii's constitution states that its redistricting commission has 150 days from its first meeting — which this year was April 13 — to finalize election maps. However, that deadline will be impossible to meet given the data delays. State lawmakers have asked the attorney general to petition the Hawaii Supreme Court, requesting forgiveness for missed deadlines.
