Indiana completed the task in 2012. I believe at least one or two other states have also done the job.
Georgia - supposedly a 'purple' state this election. Florida, the same for a while. North Carolina, too. Illinois, reliably corrupt. Can anyone explain Iowa being a swing state? New York and New Jersey - see Illinois. The rest are not big fish, and are perhaps even just cover (in as much as any state is free of voter fraud).
At a later point we will see more lawsuits covering more states - if this flies. The big prizes are the states that Trump swiped from Clinton - Michigan, Pennsylvania, etc., that have probably been voter frauded away for the past half dozen elections. Even California is on the table - take away the illegal vote and California is not so reliably Democratic any more.
