#2020Census data is coming this week. Voting districts will be finalized based on this data, and these districts will be in place for the next 10 years.

Voters deserve #FairMaps. That's why CLC is relaunching https://t.co/j8LXDDqtai. [Thread🧵]

.@Chris_T_Kenny and @michalmigurski wrote a great API for @PlanScore in R. Enables you to easily extract a variety of data on new districting plans, including local government plans being developed now across the country. https://t.co/O55F4ywNqI

In today’s @washingtonpost @monkeycageblog, @hezaproject, @michalmigurski, and I show that in the most recent redistricting cycle commissions generally drew fairer and more competitive maps than politicians.

[Chris Warshaw @cwarshaw]

Now that redistricting is nearly done, @hezaproject, @michalmigurski, and I have a new paper forthcoming in Publius: The Journal of Federalism that provides an overview of the Congressional & state legislative districts that were drawn around the country. https://t.co/DSJpmR2F3e

New work in nationwide redistricting and partisan advantage tracking from the @IPPSR team at Michigan State University!

Which party do new redistricting maps in each state favor against neutral benchmarks? Find out in our new @IPPSR Partisan Advantage Tracker, led by Jon Eguia

Nice use of @PlanScore showing the NY maps to be almost perfectly fair. This is unalloyed good news for the state senate, though not for Congress where a fair NY map fails to offset Republican gerrymanders elsewhere.

[sara sadhwani @sarasadhwani]

This is not acceptable. Bipartisan, independent commissions are the key to upholding our democratic institutions #redistricting

[Nicholas Stephanopoulos @ProfNickStephan]

This is @PlanScore's evaluation of the plaintiffs' proposed NY congressional map: It's about as biased toward Republicans as the enacted plan was toward Democrats.

Florida’s new Congressional map shows strong pro-Republican bias across all of our metrics.

[Simone Leeper @SimoneLeeper]

I could keep going all day about the problems with this map, but I need to stop tweeting and start lawyering, so here's my TL;DR: This map is a blatant partisan gerrymander, flying in the face of FL voters who made clear at the ballot box that they want fair, nonpartisan maps.

Good @boltsmag article on 2022's state Supreme Court elections, which could lead to courts that green-light Republican gerrymanders in NC and OH later this decade. https://t.co/SSMDd5UVGZ

@meyerjef @RRHElections Declination metric offers a great view into how close districts can be used to tilt the balance.

@districks Derp, sorry, forgot about the gain.

Two notably well-balanced US Congressional district plans have entered the chat.

North Carolina’s court-ordered 13 seats with an efficiency gap of just 1.4%: https://t.co/mp8NPa31VQ

Pennsylvania’s 17 seats with a tiny 1.8% EG: https://t.co/eLQBbOoB1s

210 years ago today, the map that gave us the term gerrymandering became law (though the famous cartoon wouldn’t be published until March 26 - they didn’t have @davesredist or @PlanScore back then)

[PlanScore @PlanScore]

Excellent group effort going on in redistricting this year, everyone building on each other's selfless work in pursuit of fair maps

This is very cool: In an expert report for a new lawsuit challenging MI's legislative maps brought by the League of Women Voters, @cwarshaw cites data calculated by @DKElections https://t.co/rcXicGnNUW

[PlanScore @PlanScore]

Nick succinctly reviews findings from a paper evaluating US House plans in the current cycle with PlanScore: More fair on partisanship, commissions are good, competitiveness has dropped in GA, IN & TX, and black voters are losing representation in AL & SC

Check out this awesome new paper by @hezaproject @michalmigurski @cwarshaw. It's the most rigorous study of the current redistricting cycle -- covering congressional AND state legislative maps.

The Alabama plaintiffs made use of @vest_team data. The Virginia special masters used VEST data. The NC court calls for gerrymandering measures found on @PlanScore, which uses VEST data. Really proud to see our behind-the-scenes work over the past 4 years result in fair maps
