This is a fascinating TL with some wonderful graphics. I hope it'll be continued, because it clearly has a lot of potential left in it. My only criticisms would be with some of the post formatting; while the overall narrative is clear, the sentences themselves can be a bit confusing at times. Oh, and some of the images on the American Political Parties post are no longer loading, though I assume that's unintentional. Overall, I'm interested to see if/how you'll develop this concept further!
