This has NOTHING to do with wining. It has everything to do with delaying. In WI the incumbent in a contested election does not retain his position. IOW, Prosser’s seat is empty until the election is settled. They want the union case to get to the WI SC before Prosser is seated again.
Prosser is still on the court. The election was for the next term, which doesn’t start until August.
So they would have to delay both this recount and the court case until after August 1st.
