How Nationalized are American State Publics?

How nationalized are American state publics? This paper asks how well a revealed liberal-conservative continuum can explain the attitudes of more than 180,000 Americans, 2016-24. It then uses these scores to make comparisons among and within subgroups. A regional difference opened up between 2020 and 2024, such that respondents in the Northeast and West now exhibit higher attitude constraint than those in the South and Midwest. However, this may be due to the kinds of people in each place rather than any factor inherent to region. No state registers statistically significant change, but most trend toward higher dimensionality. Most other results are consistent with expectations from the parties and behavior literatures. Finally, there is prima facie evidence of dealignment within all subgroups (party identification, race, gender, degree attainment, and political knowledge).
