Dems had some huge wins in ALL of Tuesdays special elections, great looking chart!

11. The numbers are a bit confusing.

As I read it, the 2016 and 2020 columns are not totals but are also "margins" (ie, % of vote that went Dem minus % that went Rep). And these are some very, very blue districts, except for NH, which actually flipped R->D.

So the D margin has increased in all of these districts, which is great, though where that final figure of 4.6% (the 2023 average) comes from isn't obvious. All the other margins in the blue column are much higher, ranging from 6.9% to 33.3%. Perhaps I am missing something....
