Randall Munroe, Kelsey Harris, and Max Goodman for xkcd mapped all the challengers for the the upcoming midterm elections. Names are colored by political party. They are sized by the level of office a candidate is running for and the chances of success. (I’m not totally sure how that scale works though.) Interact with the map to focus on regions, and click on names, which directs you to the candidate’s election site.
Wow.
