This is a really useful paper for thinking more carefully about what we mean by “proportional representation.” @jacksantucci.bsky.social shows that STV and party-list PR shouldn’t simply be treated as functionally equivalent as rankings and transfers can meaningfully alter party-level outcomes.

Here's the latest version of my working paper on the categorical difference between STV and (list) PR and how not appreciating it may have led, on the basis of U.S. data, to conventional wisdom that PR causes party-system fragmentation. jacksantucci.com/docs/papers/... Feedback welcome. More below.

Do party-list proportional representation (PR) and the single transferable vote (STV) produce different results? These reforms are hotly debated in American politics, but most answers to the question come from non-U.S. cases. This paper replicates and extends the best existing analysis of U.S. data. Gosnell (1939) simulated list PR elections from observed STV first choices in Cincinnati (1925-37) and New York City (1937), finding that majority control of government did not change across the systems. Later work took this to mean that both kinds of PR were equivalent with respect to preference aggregation. Reappraisal and extension of the study do not support that view. All else equal, voters’ lower rankings changed majority control in five of 21 elections, one of which was in the original sample. These results offer fresh perspective on ballot exhaustion and ticket-splitting, which can act as STV-specific causes of fragmentation. The paper explains simply how list PR and STV differ. It concludes with notes on research directions and extending the data to more cases.

NEW: 1 in 10 Americans now live in a different congressional district following Trump's redistricting war to rig the midterms, a report said. The result? Voters are losing faith in democracy — and the politicians who should be representing us will be more insulated from public accountability.

Sen. Mark Kelly (D-AZ) about USS Abraham Lincoln: "What's worse is the Sec. of Defense's response dismissing it like it's no concern at all. I think a fundamental part of leadership is trying to improve the lives of the people you're leading, and he doesn't want there to be any accountability"

Stanford Law Prof. Pamela Karlan joined PBS News Hour's @amnanawaz.bsky.social to discuss how proportional representation could put an end to the gerrymandering wars. Prof. Karlan joined 500+ scholars on a letter urging Congress to adopt PR and end redistricting wars for good. Watch the segment:

Remember when Trump threatened to wipe out a whole civilization? And then backed out of that and talked about forming a deal with Iran? And then dropped that and went to a UFC fight as negotiations fell apart? And then unveiled a triumphal arch and a photo of himself as Jesus? That was this week.

Pete Hegseth — the most unqualified Defense Secretary in modern history — blocked the promotion of two Black & two women Army officers. These are servicemembers who earned their rank, served with distinction, and put their lives on the line for this country — & they deserve better than this mess.

When the birthright citizenship decision comes out, people will say it could never have gone any other way, that the law was obvious. But the mere fact that SCOTUS took on the case is evidence enough that we are living in a time of democratic precarity.

A single vote for Trump in the birthright citizenship case would be as bad as anything the Court has done since Bush v. Gore. This issue has been settled for more than a century. It is the jurisprudential equivalent of asking what 2+2 is. Any answer other than 4, something is deeply, deeply wrong.
