“Higher education predicts ideological extremity”? I don’t think this data viz supports this thesis statement. In fact, it looks more like ppl with “some college” have gone over time from a unimodal symmetric dist to the kind of bimodal split seen in higher ed populations seen earlier in time.
Consider a “heat map” for each demo segment with time along the horizontal axis and vote split along the vertical. You would see the “some college” bifurcate and the others not so much, I think.
