We have far more in common with people of our age than we do with people of our region. Pocketbook interests cluster by age cohort - whether it’s social security or AI in the labor market - the most potent concerns have age-based constituencies that are today dispersed across districts, without cogent representation (you could even call this “cracking” of the youth vote in gerrymandering terms… all districting is a choice!). Furthermore, districts exist as a concept to allow for people to have representation for common interests (historically, agricultural and manufacturing, etc). Yet, age tends to be a better predictor than geography when it comes to a wide range of issues (including foreign conflict, climate change, tax policy, social mores, and public benefit structures), issues that have not seen serious public engagement or debate in large part because the constituencies are dispersed. A politics that has to build cohorts across generations would be a politics that has to grapple with the preferences of people under 40, which today, I think you could argue are largely absent from national politics.
