Today’s big partisan gerrymandering case: Maryland (Benisek v. Lamone)

March 28th, 2018, 11:40am by Sam Wang

Leaving SCOTUS now. There are almost certainly at least five votes to strike down Maryland’s partisan gerrymander, but no clarity on the equally important question of HOW the Court will do so. — Ian Millhiser (@imillhiser) March 28, 2018 So, oral arguments in Benisek just ended. Here’s the transcript! A round-up of the case is […]

Game over in Pennsylvania!

March 19th, 2018, 3:49pm by Sam Wang

Today came two rulings. First, a three-judge court turned down a challenge to the redrawn Pennyslvania Congressional map. Then, a few hours later, the U.S. Supreme Court did the same. These were long-shot cases, since they would have involved finding that the Pennsylvania Commonwealth Constitution was in conflict with the United States Constitution, for example […]

Introducing the new Pennsylvania Congressional map

February 19th, 2018, 3:20pm by Sam Wang

Here’s the new Congressional map for Pennsylvania, drawn by advisor to the court Nate Persily. I think it’s a landmark contribution to the understanding of partisan fairness, in one of the most politically heterogeneous states in the Union – “Pennsatucky.” For anyone who’s drawn such maps, this particular one is a pleasure to look at.

The following analysis is a team effort by the Princeton Gerrymandering Project. John O’Neill drew maps which he, Brian Remlinger, Will Adler, and Madeleine Parker analyzed. For other people’s plans, we cited the work of Brian Amos. In a previous post, we evaluated the Pennsylvania GOP leaders’ proposal for redrawing the congressional map and found […]

When simple rules aren’t enough

February 13th, 2018, 6:36pm by Sam Wang

As the old political-science saying goes, “all redistricting is gerrymandering.” Inevitably, choices and tradeoffs have to be made. When it comes to representation, the resulting map can end up balanced – unless partisan advantage is made the primary criterion. The Pennsylvania Supreme Court set down clear “floor criteria” for what was absolutely required in the […]

A statistical toolbox reveals Pennsylvania’s extreme Congressional plan

February 13th, 2018, 8:27am by Sam Wang

Mathematicians have been working hard to create ways to measure #Gerrymandering. 2017 was a big year on this: accumulating evidence showed PA most gerrymandered of all by two measures, among five worst by any measure. We all lose our voice when our votes don't count. pic.twitter.com/5fgCxTc00r — LWV Pennsylvania (@LWVPA) February 13, 2018 Today, Philly.com […]

Three clues that today’s proposed Pennsylvania map is still a gerrymander

February 10th, 2018, 4:38pm by Sam Wang

An image of the Pennsylvania legislature’s proposed Congressional map has been released. It appears to be nominally in compliance with the Pennsylvania Supreme Court’s order, since it splits fewer counties than the current map. However, as we have seen in North Carolina, a prettier map can still conceal ill intent. Despite the low resolution, enough […]
