The Princeton Election Consortium needs your help!

May 9th, 2018, 10:26pm by Sam Wang

Here at PEC, we need help for the 2018 season. I want to revamp the site, as well as redesign some of the ways we present information. It’s an effort for the summer, with the goal of being fully automatic by fall. Interested? See this ad, and write to us. One catch: it would be […]

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 […]

Pennsylvania’s (current) 18th CD: The top of the levee

March 13th, 2018, 9:08pm by Sam Wang

Whoever wins today’s special election to fill the open Congressional seat in Pennsylvania’s 18th District, it wasn’t supposed to be close. It’s part of a statewide partisan gerrymander, a district that a generic Republican ought to win by about 20 points. In November 2016, Donald Trump got 58% to Hillary Clinton’s 39%. The closeness of […]

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. […]

Pennsylvania partisanship, part II: Democrats in chains

February 17th, 2018, 8:02am by Sam Wang

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 […]

Justice Alito draws the line

February 5th, 2018, 11:11pm by Sam Wang

Today, U.S. Supreme Court Justice Samuel Alito denied Republican legislators’ request for a stay of the Pennsylvania Supreme Court’s redistricting decision. That decision overturned the state’s partisan gerrymander, and remains in place. Therefore the drawing of new maps will go forward. Here’s a quick rundown of what the decision does – and doesn’t – mean.

Pennsylvania Congressional gerrymander overturned – and it seems likely to stick

January 22nd, 2018, 2:51pm by Sam Wang

Update, February 5th: Justice Alito denied the Pennsylvania GOP legislators’ motion for a stay. He did so without referring the matter to the full Supreme Court. Justice Alito is one of the three most conservative members of the court, and a near-guaranteed vote against restrictions on partisan gerrymandering…based on the U.S. Constitution. I would call […]
