WISN is probably getting their info from the AP chart, and they haven't figured out it's wrong.
Look at the Waukesha county judge race. Reporting at 95% in, about 100,000 total votes. 67/33 for the good guy, by the way. I would suspect the Supreme vote count to be about the same.
Supreme Court REPORTING 88%
Joanne Kloppenburg 655,325
