RBH has submitted a ton of great crazy primary maps. States with lots of counties are more fun... Washington unfortunately loses out in this regard (we don't have townships either). Here is one of my favorites:
GA Lt. Gov D Primary, 1998:
I can probably tell you the race and region of every candidate without even knowing who they are.
I imagine that the yellow candidate is white and probably from the northern suburbs of Athens, but I wonder what explains his support in the far northwest and southeast. Comparative weakness/geographical distance of the others coupled with a more even distribution of the yellow candidate's vote, perhaps.
