> Election officials in more than two dozen states have compiled lists of citizens whom they allege could be registered in more than one state – thus potentially able to cast multiple ballots – and eligible to be purged from the voter rolls.
The problem is that it often only uses a persons name as a singular data point. So if a person votes with the same first/last name as another person in another state, it's possible that vote could be wiped out. It was even matching names even though there were differences in middle names or had Jr/Sr at the end.
The journalist, Greg Palast, who investigated this back in 2014 has been doing radio circuits again recently saying that it's still being used in a bunch of states. Not sure about the validity of this since there hasn't been much reporting elsewhere on this. He seems to be the only one talking about it. And googling 'Interstate Crosscheck' only brings up his articles and democrat superpac websites.
