Presidential Results using 100K districts. The colors and tooltips has the raw vote margin, ex. a candidate winning by 20,000 votes instead of 40%. This is the recommended way to view the 100K districts and their results, as it also factors in turnout and possible inefficiencies in a certain area. Just as an example, even if a Democratic candidate wins an urban district by 60%, if the turnout there is low, in reality they aren’t winning that area by as much as they could be.
