Ballot after ballot, #directdemocracy shows us where representation did not work.

Take today's vote on a tax break for homeowners: @leewas.bsky.social polls suggest it is largely supported by homeowners, a group with a strong lobby. Renters tend to oppose it, with ≈60% being renters in Switzerland

#POLITKOLUMNE: A plutocracy rather than a democracy? A person above the median income is electorally worth 1.16 times a pereson below the median.

In Swiss direct democracy, however, wins & defeats are distributed quite equally across income classes @leewas.bsky.social www.derbund.ch/politkolumne...

Do men see gender parity in representation as detrimental to their interests? What about when women’s representation exceeds parity? And how do such shifts affect men’s fairness perceptions? I address these questions in my article, now published in PRQ. 1/9
