Modern Family doesn't work so well because it only accounts for urban Democratic voters, i.e., rural Democratic voters such as black voters in the South, Native Americans in the Plains/Mountains and Hispanics in the Southwest don't show up. But Duck Dynasty is interesting in that rural minority voters also don't watch, so it's overall a quite strong correlation. Still seems to fall off a bit out West, though - the Central Valley of California is too low, e.g., and Arizona is off. Perhaps a climatic issue.
Its only good as a weird 'a-ha' thought in regards to white educated voters in 2016 swinging towards Hillary.
Its strange to think of but back in 2012 a lot of Romney voting suburban precincts voted No to banning gay marriage in North Carolina, despite the 61% in support in the state overall. These are also precincts where a high percentage of people said they migrated from a different state. The suburban educated precincts of america that might of supported the GOP because of their association with voting republican as synonymous with economic success, having less support for bans on gay marriage was a future predictor of the places that republicans fell back in 2016 compared to 2012.
I hope im wrong but the thing that scares me is how politics is sorting itself on cultural lines. The amount of cultural suburbanites voting republican will switch but so will cultural rural americans further turn towards the GOP.
Duck Dynasty and other white cultural signifiers don't show up amongst black americans in the south for the reason that it appeals to a white rural audience, like the amount of chinese and indian americans you find in cities who like country music is a minuscule amount for the same reason.
Here's a show named Empire that i've personally never have heard of before. Theres a strange amount of native american areas that watch it but most of it is correlated with the demographics of black americans.
