@gelliottmorris.com's piece on what Americans actually want from parties is fascinating. It also (re-)produces a classic finding: Almost no one is in the "socially liberal but economically conservative" bucket, but those who are have very popular Substacks

The hidden axis: the left-right spectrum has a non-ideology problem
Most voters want a party that emphasizes cost of living issues and makes the world a better place. Few Americans think in solidly ideologically terms. "Moderates" are mostly non-ideological.

Great way to visualize the distance between poverty and different income levels
I decided to convert dollars to centimeters. That allows us to visualize, for example, the distance between having no money and being at poverty level — about four city blocks.

You can even make a (formal) argument that it can lead to more intense partisan positions at the expense of running on broad appeals.

Elon Musk called it a scam.
But really it's a long-standing electoral practice of New York.

electoral reform is very popular in the US. there is a broad devotion to the idea of fairness. PR can get us there and is one popular option, but not the only one
Wow! That's a lot higher support level than I expected. And that 32%"don't know" means there's a high ceiling

And all of the sudden, everyone’s about to become an expert in Dutch parliamentary politics
It‘s going to be a wild ride tomorrow when pundits around the globe explain to us what kind of party D66 is and why they did exactly what they have always told us their favorite strategy is
And just to emphasize it again: yes, PVV is down by a lot but the other two far-right parties are up by a lot

Mills would be 79 when she takes office, 85 when she retires. Says she'll only serve one term, which shows how useless term limits are to bring down the age of Congress. To bridge the age gap, we need serious reform, as @oscarp.bsky.social and I recently wrote: protectdemocracy.org/work/age-div...

Some graphs from our report on the age divide that really struck me: Almost 40% of US representatives are above retirement age and that is a uniquely American problem.
It also doesn't seem like term limits would help much: new members of Congress are...not that young!
