Our new working paper (w/public data!) shows that anti-vaccine state policymaking nearly doubled following COVID-19. Republican state lawmakers are overwhelmingly responsible for this trend.

Just posted my evaluation of what happened in the 2024 election, based on CHIP50 data. The TLDR is that the 2020 to 2024 shift was mostly a backlash of younger individuals against what had been a pretty lousy 4 years for them.

Biden's claim that he would've won in Nov. isn't backed up by most polling data.

It also ignores the tremendous impact Harris' campaign had on fundraising for Dems down-ballot, which we document in a naturally-occurring experiment conducted before/after Biden dropped out.

Concerns about supply shortages have no influence on public support for physicians' ability to prescribe ozempic off-label. But, concerns about potential health risks do.

Re-upping this working paper, in light of news that bird flu has been detected in raw milk in CA.

Lack of concern about the dangers of raw milk could undermine our policy response to bird flu's increasing public health risks.
