🚨 NEW paper out in @PSRMJournal with @lockhartm, Huber, and Gerber: Common polling methods can significantly overestimate attitude change. We show a null effect of Trump’s felony conviction on vote choice using eight-wave panel data. 🔗 cambridge.org/core/journals/…

Scoop: The top lawyer at the Treasury Department suddenly stepped down on Monday. Comes in the wake of the Trump admin's $1.776 billion "anti-weaponization fund."

Bill Cassidy becomes the first incumbent senator to lose a primary since Luther Strange in 2017 Before that — Dick Lugar in 2012

⚖️ Do major campaign scandals change voters’ minds? ➡️ @lockhartm G. Huber, A. Gerber, J. Walker II show Donald Trump’s felony conviction had virtually no effect on his supporters, while common survey methods produce conflicting estimates cambridge.org/core/journals/… #FirstView

Just dropped my second Substack post! Using broadcast news transcript data, @cantstopkevin and I look at how media consolidation is softening news coverage of Trump. We also have an app that we’ll launch soon where folks can track broadcast and digital news coverage of the president across different outlets. Stay tuned! medium.com/Zoe.kava/how-m…

@YamilRVelez @YaleLawSch @PUPolitics @NSF Thanks Prof. Velez! Your experimental research course played a big role in my decision to pursue empirical political science.

@walkerdjack @YaleLawSch @PUPolitics @NSF Congrats!

Change of plans! I’m excited to be pursuing J.D.-Ph.D. study at @YaleLawSch and @PUPolitics. I’ll head to Princeton as an @NSF Graduate Research Fellow this fall and begin at YLS in 2027. Thanks again for the support.

How can we measure whether an event impacts public opinion? Our new @PSRMJournal shows the Manhattan trial had no effect on support for Trump and that leading cross-sectional methods fail to identify the "real" null effect uncovered by panel designs. doi.org/10.1017/psrm.2…

Excited to see this published! Here’s my earlier thread summarizing our findings: x.com/walkerdjack/st…

THE HOUSE just funded DHS by voice vote. 76-day DHS shutdown is over. They didnt even take a recorded vote

@lockhartm @ColumbiaLaw @PUPolitics Thanks Mac. A lot of what I know about political science I know because of you!

@walkerdjack @ColumbiaLaw @PUPolitics Congratulations Jack! Looking forward to following your research as you go!

I’m excited to be starting a PhD in political science at @Stanford as an NSF Graduate Research Fellow in the fall. A big thanks to my mentors at Yale and Wesleyan for their ongoing support.

Light a candle in memory of the Voting Rights Act, which died today, aged 60. Sure, Section 2 wasn't officially struck down. But it might as well have been. It's now useless to minority voters under virtually all circumstances.

WASHINGTON (AP) — Supreme Court voids majority Black congressional district in Louisiana, boosting Republican chances.

Ever since the Pentagon-Anthropic drama, talk of AI nationalization has been growing. But what would this actually look like in practice? We spoke to a dozen former Pentagon and Trump administration officials, AI-policy experts, and legal scholars. Here's what they told us:
