The New York Times’ Upshot blog recently released a fantastically detailed interactive map of the 2016 election and it is epic. It shows every neighborhood-level voting precinct in America with a breakdown of the 2016 presidential election results:
A few things I found interesting:
My town (Danville, Kentucky) looks like this. To me, this map is showing that Danville is a politically moderate city in terms of voting behavior, but that it has a slight Republican edge when it comes to presidential voting. Most precincts voted for Trump somewhere between 50%-60% and Clinton between 35%-45%. Not surprisingly, the strong Clinton precinct is where Centre College is located. The mix of different shades of blue and red tell me that there’s a good deal of political diversity in Danville. One of the objectives of the interactive map is to show you whether you live in a “political bubble” or not. Danville residents, for the most part, do not. (The rural precincts of Boyle County, however, went much stronger for Trump.)
I grew up in Cache Valley, Utah. It is interesting to see that Evan McMullin won a majority in several precincts, and enough to dilute the Republican vote to where Trump won a slim majority in most of the others. It also enabled Clinton to win a plurality in many precincts with only around 40% of the vote.
Likewise, Provo is one of the most conservative communities in the country, and McMullin won a majority in several precincts and a strong plurality in several others.
There is much more to be explored: https://www.nytimes.com/interactive/2018/upshot/election-2016-voting-precinct-maps.html
