The Times’s interactive map of precinct results shows that even within partisan strongholds, there are contrary-voting enclaves.
This feature that shows the 2016 election results at the precinct level is astounding, revealing, and a testament to the difficulty of putting all this information together. The built-in features in this interactive map to explore selected “voter islands” and one-sided places are especially helpful, but much like Google Earth, many people are eager to zoom in to their own neighborhoods. The article that accompanies the interactive had some excellent case-studies at a variety of scales. Geography always matters and the maps reveal so many telling patterns.
