A spatial exploration of the ‘halo effect’ in the 2016 US presidential election

Was the ‘halo effect’ (proportion of immigrants in surrounding area) correlated with GOP vote proportion in the 2016 election? The halo effect has been studied in Europe, where it has often been correlated with far-right voting patterns. This paper examines the halo effect and uses geographically weighted regression to explore whether the effect varies spatially.
