Interesting they went stronger for Biden in RI than MA.
Is Rhode Island the last redoubt of the "White ethnic blue collar Democrat"?
Pretty much, yeah. RI's generally more "downscale" than MA, arguably the most in New England. It has fewer minorities (particularly black - 5% to MA's 11%, which certainly adds to MA's Democratic lean), and RI whites are less college educated than MA whites, yet it's almost as safe for the Dems (arguably even more so on the state level). So that basically necessitates that white ethnic blue collars are voting for Democrats, because of course, RI does have its share of Republicans.
