There is no political topic that can get people’s blood boiling quite like partisan gerrymandering. Many even go so far as to call it an afront to our democracy. But what do we know about how effective it is and what the data shows about its outcomes?In a new paper, “Widespread Partisan Gerrymandering Mostly Cancels Nationally, But Reduces Electoral Competition” Princeton political scientist, Kosuke Imai, uses a novel methodological approach to try and document the effect of partisan gerrymandering. What he finds is surprising and may lead people who participate in it to re-think whether it’s worth the effort.Link to paper: https://www.pnas.org/doi/10.1073/pnas.2217322120
