Welcome! US maps are organized by the four geographical regions used by the US Census (West, Midwest, Northeast, & South), with non-US maps in the "International" section, and can be found at the top bar. Unless stated otherwise, every election map depicts the margin of victory as opposed to the winner's share of the vote, and every map uses TIGERLINE shapefiles from the US Census Bureau for county boundaries.
Important note about international maps:
While I do my best to research and understand elections, I am NOT an expert in any non-US politics. Furthermore, my analysis is limited by my inability to speak a language beyond English (although I am working on learning German). As such, I would highly recommend doing further research if a particular election interests you, and I would encourage you to seek out sources from that country. Additionally, getting data/shapefiles for international elections tends to be more difficult than in the US, which is why I haven't made a ton thus far.
Finally, as noted below, this is not a commercial project, and so maps may be used for non-commercial purposes as long as appropriate credit is given (mainly my name and, if possible, a link to this site).
