“…Gollwitzer et al (2020) measured aggregate movement data from cell phones as a function of county vote share in the 2016 election and found the extent to which people traveled outside of the home during the early months of COVID, when stay-at-home mandates were in effect, varied by county-level partisanship even when controlling for numerous factors that could explain away the relationship (for similar results, see Allcott et al, 2020; Barbalat & Franck, 2022; Barrios & Hochberg, 2021; Camobreco & He, 2022; Grossman et al, 2020; Im et al, 2021; Kavanagh et al, 2021). Once vaccines became available, uptake also followed partisan patterns (Leonhardt, 2021), and mortality eventually reflected these differences (Bernet, 2022; Neelon et al, 2021; Sehgal et al, 2022; Wallace et al, 2022).…”
