Do you want to move the needle on who controls the House? Use the cool app in the left sidebar to locate competitive House districts near you. Also, use the donation links, which lead to either major party. Democrats will gain seats – but they face a major barrier to gaining a majority. Tonight (Wednesday), [...]

An online app to diagnose partisan gerrymandering

June 26th, 2016, 11:30pm by Sam Wang

Today, Mark Tengi and I release an online application to help diagnose whether partisan gerrymandering is evident in a set of election results. The application is intended for the use of judges, clerks, litigants, and others who want a statistically well-founded and easily understood test for partisan asymmetry. The Supreme Court has suggested that partisan [...]

SCOTUS upholds Arizona Redistricting Commission!

April 20th, 2016, 10:24am by Sam Wang

Decision’s out (PDF)! It’s unanimous, written by Breyer, favoring the Commission, an outcome for which I had advocated. Unfortunately, nothing about tests for symmetry, which I proposed in the NYT and in an upcoming Stanford Law Review article. More thoughts…

On the passing of Justice Scalia and this year’s voting rights cases

February 14th, 2016, 10:04am by Sam Wang

An underappreciated fact about the U.S. Supreme Court is just how often its decisions are unanimous, or nearly so. In past years, the two justices who disagreed the most often were Ruth Bader Ginsburg and Samuel Alito – and even then, they only disagreed about one-third of the time. Above is a visualization of “disagreement [...]

Attending oral arguments in Harris v. Arizona Independent Redistricting Commission

December 20th, 2015, 11:39pm by Sam Wang

Dec. 25th: Updated with five more FantasySCOTUS predictions. The median outcome still favors the Commission, by a narrow 5-4 majority. In my NYT piece proposing statistical standards to detect partisan gerrymandering, I focused on Harris v. Arizona Independent Redistricting Commission, a current Supreme Court case [SCOTUSblog] [Blog for Arizona]. On December 8th I attended oral [...]

The effect of gerrymandering in four states exceeds that of population clustering in all 50 states

December 8th, 2015, 7:00am by Sam Wang

My New York Times piece was specifically focused on the legal question of what a party-neutral standard should look like. It didn’t address the political question: where do such deviations come from? As it turns out, the answer is: post-2010, partisan redistricting accounts for more than half of the total asymmetry in the House. The [...]

Can Math Help Save Democracy?

December 5th, 2015, 10:41am by Sam Wang

In the New York Times I have a piece in the Sunday Review, “Let Math Save Our Democracy.” It describes some simple statistical standards for partisan gerrymandering, and how they might resolve an upcoming Supreme Court case (Harris v. Arizona Independent Redistricting Commission) quickly and definitively. It’s based on my law article, “A Three-Prong Standard for [...]

Redistricting battles everywhere

December 4th, 2015, 10:27pm by Sam Wang

Bloomberg Politics has an excellent interactive on redistricting battles (ht/ to reader bks). While we’re on the topic, make sure to read the New York Times this weekend. I have a piece on gerrymandering standards in the Sunday Review section. Other entertainment: here’s a cool general-election demographic simulator by Aaron Bycoffe and David Wasserman.

Two Cheers for Ohio Redistricting Reform

November 4th, 2015, 10:16am by Sam Wang

Yesterday, Ohio voters overwhelmingly approved Issue 1, an initiative that sets up a bipartisan commission to oversee redistricting of state legislative districts. This is a great step in combating gerrymandering. However, there are some fine points that have to be resolved for it to work well.

Offering a new standard for gerrymandering to the Supreme Court

November 2nd, 2015, 2:58pm by Sam Wang

Tweet // Today, I filed a friend-of-the-court brief in the Harris v. Arizona Independent Redistricting Commission case (S. Ct. 14-232). The brief can be found here (for a summary of other briefs, see the Arizona Eagletarian blog). In it, I argue that the Supreme Court should reject Harris’s case on the grounds that there was [...]
