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.

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. papers.ssrn.com/sol3/papers.…

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.

This is not acceptable. Bipartisan, independent commissions are the key to upholding our democratic institutions #redistricting
#NEW: GOP lawmakers have introduced a joint resolution to abolish the Michigan Independent Citizens Redistricting Commission. tinyurl.com/bstfcbbz

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.

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)
#OTD in #history, 1812, #Massachusetts Gov. Elbridge Gerry signed into law a senate map that sought to advantage his party. The drawing of one district was so byzantine, it resembled a salamander. Critics combined Gerry & salamander to create the popular portmanteau: gerrymander.

Pennsylvania Legislative Reapportionment Commission (@PaLegis) released their final approved state legislative plans last Friday - find their partisan skew analyzed across several metrics on @PlanScore's library: planscore.campaignlegal.org/…

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

Excellent (and disturbing) analysis, using @PlanScore, showing that the severe pro-Republican biases of many state legislative maps will endure for another decade. In many ways, we're still living in the world created by the 2010 election. pewtrusts.org/en/research-an…

🚨🚨🚨 My latest @PPICNotes blog, with Jennifer Paluch, evaluates CA's final redistricting plan on racial/ethnic representation and partisan outcomes. tl;dr: there's a big increase in Latino representation and a slightly stronger tilt to the Dems. 🧵 1/ ppic.org/blog/racial-represe…

What does undoing gerrymandering look like? In a 50-50 election, Republicans would win nearly 62% of congressional seats under current lines drawn by GOP. Under new plan ,adopted by independent redistricting commission yesterday, they would win about 55% (via @PlanScore)

I just testified using metrics produced by @davesredist @princetongerry and @PlanScore helping the commission see that these plans are partisan gerrymanders.
