Another Commenter for Hire,
Stop and think about it. Voter lists have been provided for years, at least 40 years that I know of here in Alaska. 
There was no Commission around then, only political parties, political operatives, pollsters, marketers, unions, and noisy people who want and use them. They are the people who want access to the voter lists.
Now a federal commission is asking, not demanding, for voter lists with public information.
Same information lots of people got about ten months ago and months before that.
I changed my Party status to NP, because I no longer believe in the two party system.
As far as what it has to do with stopping illegal voting, nothing because the only way to stop it (future) is to issue at no charge a voter card with your photo and or finger print.
As far as finding out if illegal voting occurred (past tense) I imagine some "genius" has come up with a computer formula or program to feed all information into, compare previous elections to the 2016.
