Easy.

Sue the states for not complying with the National Voter Registration Act and at the SAME time, the commission can just purchase the data (minus the SSNs) from each state.

The argument that, "There IS no voter fraud so we DON'T need to commission a study" is just ludicrous.

We DON'T know the extent of of voter fraud (and we absolutely know that SOME exists) because we HAVEN'T commissioned a study that examines every state.

 If we can spend all this time and money investigating whether or not there was "collusion with the Russians" in attempt to tamper with the election (and that's looking more and more like a JOKE) we can CERTAINLY take the time to make sure that ONLY AMERICAN CITIZENS votes are being counted during our elections.

The data itself is available to the public (even if it's for a "fee") so not giving the data over because of some sort of "privacy issues" is obviously just an excuse to cover up the EXTENT of the voter fraud we KNOW is occurring in certain states.
