The only ways would be to either get a change past a Governor Jim Doyle (D-Madistan) veto (the Pubbies only hold a 19-14 advantage in the state Senate and 60-39 advantage in the Assembly, not enough to bust a veto) or have the US Attorney find a federal hook (the DAs in both Milwaukee and Dane Counties, as well as the Attorney General are all DemonRATs).
And here's the kicker - to my knowledge, NONE of those 81,500 were ever verified. At the time of a hearing on election reform in 2001, the Milwaukee Election Commission stated they were too "overwhelmed" entering the data into their system to send out cards to verify the validity of any of those 81,500 votes!
