On Bluesky, you often see commentary on and jokes about clips from White House Daily Briefings--but have you considered *why* the White House does them? And to what end? I (with @benjaminsnoble.bsky.social and Erin Rossiter) investigate in a new paper 1/N www.davidryanmiller.com/files/Presid...

‼️ New working paper ‼️ We find bipartisan appeals credibly signal policymaking intentions—on an issue-by-issue basis We show how and why bipartisan lawmaking persists amid congressional conflict: progress often comes through issue-specific pathways rather than broad consensus between Ds and Rs 🧵👇

So excited that my book with @allisoncarnegie.bsky.social, Global Governance Under Fire: How International Organizations Resist the Populist Wave, will be published with @princetonupress.bsky.social on January 27, 2026. You can pre-order the book now for 30% off with the code P329 at the below link!

Today I am thankful for the SPPQ editorial team! I created a simulated social media environment in Qualtrics and found that individuals’ political attitudes can change based on state legislators’ social media posts. A dissertation chapter and the most fun I’ve had working in a project so far.

Congratulations to the RPL Lab on their BJPS publication, supported by the Rooney Institute! The study examines how state legislators were held accountable for actions challenging the 2020 election, finding only Jan. 6 participation led to consequences. doi.org/10.1017/S000...

Political inexperience in Congress has measurable effects on legislative outcomes. Our research finds that when districts elect political newcomers over career politicians, congressional dysfunction tends to increase. New explainer of our PNAS study: theconversation.com/amateur-hour...

Since 2018, Republican candidates have completely erased a massive Democratic edge in emphasizing education issues.

I agree with this --- CampaignView (campaignview.org) data for 2024 should be released in the next few weeks, but across select issues, we find modest movement left by House Dem candidates (at the issue level) in recent years. Both parties moved to the extreme on energy issues (1/2 sd).

I haven't spent a ton of time working through this, but it draws heavily on national party insights to make recommendations for Dem candidates... who are already doing these things? Over three-quarters of Ds discuss economics, healthcare etc.... campaignview.org www.nature.com/articles/s41...

Important thread on the "aren't Dems already doing the things you're telling them to do" angle

Look. It would be great if there was one simple trick for winning elections. But 'just be more moderate' isn't it. In fact, you can use the NYT's exact method to 'prove' a 'Progressive Advantage' of +1.4 pts. This piece shows what's really going on: funded candidates do better than unfunded ones.

Every cycle, we relearn the same lesson: candidates without governing experience can become liabilities fast onlinelibrary.wiley.com/doi/full/10.... www.pnas.org/doi/10.1073/...

Congratulations to Rachel Porter, Jeff Harden, and Mackenzie Dobson on their new publication in PNAS! Their article, "Electing amateur politicians reduces cross-party collaboration," stems from research conducted in the Representation and Politics in Legislatures Lab. www.pnas.org/doi/10.1073/...

Currently in FirstView: In “Balancing Precision and Retention in Experimental Design,” @gustavodiaz.org and Erin Rossiter study how experimental design choices can increase precision when estimating treatment effects. Specifically, they examine block-randomized and pre-post designs.

Great thread. One of the reasons political scientists typically don't like term limits.

Just published at PNAS (@pnas.org): “Electing amateur politicians reduces cross-party collaboration” We show that districts electing first-time members of the U.S. House experience substantial declines in bipartisan representation in the subsequent Congress. 🧵1/4
