A useful guide to recreating in ggplot2 the style of the figures from one of my reports #rstats

We wrote about this in 2022 - and the divergence seems to have continued since. We wanted to see what types of districts each party represented in 2020/2022, what competitive districts looked like, and what that means for the coalitions parties need to win in a winner-take-all system.

Majoritarian electoral systems offer very limited pathways for minority representation and the Supreme Court may soon block one of the most crucial ones. What are the alternatives? Mike Latner and I take on this question in this piece ⬇️ houstoninstitute.substack.com/p/pathways-t...

How do minority groups achieve representation under different electoral systems? In this explainer written with Mike Latner, we describe the pathways to representation under majoritarian/plurality systems, ranking systems & proportional systems. houstoninstitute.substack.com/p/pathways-t...

Very cool to see our report on the age divide referenced in the latest @marketplace.org podcast: www.marketplace.org/episode/2025...

I'm so deeply saddened by the passing of Kimuli. She was an incisive scholar of comparative politics, generous with her advice and feedback, and had the most infectious of laughs. fas.columbia.edu/news/memoria...

I wrote about some of the research on this here - but as Jack points out, it's important to note that context matters and electoral institutions are not determinative. www.newamerica.org/political-re...

I thought death by lightning was great, but still annoyed that one politician from NY in the show said he liked the cherry blossoms in DC when cherry blossoms didn't arrive to DC until 1912.

🚨New genAI teaching material: an Electoral System Explorer built with Claude. It lets students see how votes translate to seats under different electoral systems. Try it here: claude.ai/public/artif.... Feedback, as always, is very much appreciated! #poliski

I deactivated instagram back in May and haven't looked back since 🙌

@gelliottmorris.com's piece on what Americans actually want from parties is fascinating. It also (re-)produces a classic finding: Almost no one is in the "socially liberal but economically conservative" bucket, but those who are have very popular Substacks www.gelliottmorris.com/p/not-just-l...

Outstanding analysis. Now if only we had an electoral system that could reflect this! substack.com/home/post/p-...

Great way to visualize the distance between poverty and different income levels

Why were some NYC candidates listed twice? The short answer: fusion voting. @oscarp.bsky.social explains how and why it's used for @thefulcrum-us.bsky.social: thefulcrum.us/governance-l...

You can even make a (formal) argument that it can lead to more intense partisan positions at the expense of running on broad appeals. osf.io/preprints/so...

Elon Musk called it a scam. But really it's a long-standing electoral practice of New York. In this piece, I explain what fusion voting is and why there's a movement to revive the practice in other states: thefulcrum.us/governance-l...

electoral reform is very popular in the US. there is a broad devotion to the idea of fairness. PR can get us there and is one popular option, but not the only one

If you want to read more about Moon Duchin's work, here's a study she and her team did for @newamerica.org on how more proportional electoral systems could enhance representation in Massachusetts. www.newamerica.org/political-re...

Marathon day in NYC and perfect fall weather = city wide block party

And all of the sudden, everyone’s about to become an expert in Dutch parliamentary politics

huh - a quirk of Monaco's electoral system: "In case of a tie, the eldest candidate is declared elected." archive.ipu.org/parline/repo...

Mills would be 79 when she takes office, 85 when she retires. Says she'll only serve one term, which shows how useless term limits are to bring down the age of Congress. To bridge the age gap, we need serious reform, as @oscarp.bsky.social and I recently wrote: protectdemocracy.org/work/age-div...

Highly recommend this book by the incredibly talented Haley Cohen on the gripping, harrowing, but ultimately inspiring story of the grandmothers of the Plaza de Mayo. www.simonandschuster.com/books/A-Flow...

Finally got around to reading this excellent novel (You Dream of Empires in English). Highly recommended!

Have I got the report for you! www.newamerica.org/political-re...

Some graphs from our report on the age divide that really struck me: Almost 40% of US representatives are above retirement age and that is a uniquely American problem. It also doesn't seem like term limits would help much: new members of Congress are...not that young!

“An uncommon animal, called by naturalists a GERRYMANDER,” Ohio State Journal, August 31, 1842. From @leedrutman.bsky.social's essay on previous gerrymandering wars and how to fix the problem once and for all (proportional representation!) leedrutman.substack.com/p/what-the-a...

Excited to go to New Orleans this week for @netrootsnation.bsky.social. I'm on a panel making the case for proportional representation in the US. Come check it out if you're around!

This reminds me of this recent paper that came out on how rare it is for democracies to come back after backsliding. Though quite the sobering read, it is also an invitation to imagine and work towards better institutions to future-proof democracy. www.journalofdemocracy.org/articles/the...

Instant run-off results from last week's election are out. Mamdani wins 56% of the votes in the third round, 12 points ahead of Cuomo.
