We pride ourselves, as Americans, on the idea that we root for the underdog. We dont want the Patriots to win; we want the Eagles. We dont want Cobra Kai to win; we want Daniel to do that swan-kick thing. And we say we dont want the Yankees to win their 200th World Series but, tragically, we do. Deep in our American hearts, it seems, we want the rich unsympathetic bullies to continue their baseball dominance. Deep inside our American spirit, theres a murky shadow.
Anyway, we took that Facebook data and did politics to it.
Here was our thinking: What if we took the county-level baseball fan data and compared that to county-level 2016 election results? In theory it would allow us to see the places that were both most supportive of particular teams and most supportive of individual candidates. It isnt perfect: We basically applied the percentage of fans of each team in a county to the number of votes cast for Donald Trump, Hillary Clinton and third-party candidates in each place. But overall, the results are clearly representative.
We begin at the 10,000-foot level. Here is each team, represented by a pie chart showing the total number of voters favoring each team (the size of the pie) and the split of votes among those fans (the pie slices).
