Looking now like David Prosser will hold on to a narrow victory in the final count with about 50.2% of the vote.
From the Huffington Post, a map showing the county-by-county change from Scott Walker’s share of the vote to David Prosser’s. The image on the original post has a nice mouse-over where you can see the actual numbers. At first glance, the picture doesn’t bode well for Wisconsin politics — the most Democratic parts of the state got more Democratic, and the most Republican parts got more Republican. (Or so it looks — I didn’t, y’know, actually make a spreadsheet.) Combined with the inevitable bitterness that follows a close election, I think we’re looking at another couple of years of state politics carried out in Manichean deathmatch mode. People with direct knowledge tell me the State Supreme Court has been operating that way for years already.
And here’s a map showing the geographic distribution of ethnicities in Wisconsin in 1900. The Democratic/Republican line from northwest to southeast is also the Norwegian/German line.
