Wisconsin's election bureau, the GAB, has made precinct results available for the Supreme Court race for all but three counties. We're trying to match these results up with state Senate districts. Jeff and I took a couple of passes at it, and you can see what we've done so far on Google Docs. Supreme Court race results are in the first tab, and district locations are in the second tab. Highlighted column K in the first tab is where things stand at the moment, but you'll see there are still a number of "#N/A" errors. These can either be corrected manually (if people have the time & inclination), or perhaps they can be solved programmatically, if there are any Excel geniuses out there. (The problem lies in split municipalities - wards are often broken up differently in the Supreme Court data than they are in the district locations data in the second tab.)
Anyhow, if you're interested, please take a look and see if you can't help us polish this data set off. This information will be very valuable in the coming recall elections.
