Your article doesn't say they will, nor can you show that anyone was removed.
Show me where a Secretary of State, of any of the 28 states that use this program, has actually removed someone from the voter roles due to this program's information.
The article says Georgia used the list to send out a postcard, asking the recipient to return the card verifying their registration. And what anyone with any sense knows are several things pointed out in the article - most of us ignore postcards as the junk they are 99% of the time, so there's a very, very good chance the card will be overlooked and not returned. Also, the person may have moved, and never get the card, and the poor who rent are far more likely to move than those with a home, the card lost in the mail, etc. And there is no follow up - no phone call, not letter, no nothing.
The whole point of something like this is to add any step that voters you don't want to vote to have to take before they can cast a ballot. If you make those voters take an additional step, you KNOW many will not or cannot for various reasons, and they won't vote. So the only real problem is designing a process that makes the other party's voters do this more often than your own, which the list does - minorities are over represented by about 550,000 on the lists in VA, NC and GA, and whites under represented by about 550k. The numbers are staggering - hundreds of thousands in the states examined. If 400,000 post cards are mailed based on bogus matches of double voting, 80% return the card, that's 80,000 removed from the rolls. If the split is 60 democrats/40 republicans, you've just removed a net 16,000 likely democrats from the rolls.
Sheesh, this is how ELECTION fraud works, it's done by consultants in suits and white shirts making $1,000 an hour to legally tilt the process in favor or their candidates. And not one conservative on here applauding photo ID rules seems to have the slightest problem with error ridden lists being used to purge registered voters off the rolls.
Besides, the reason you know this is BS is there has never been any actual use of the "double voting" list to prosecute more than a handful of people. The article talks about NC - they have a list of nearly 200k and have prosecuted NO ONE. NOT ONE VOTER.
