@marcelias Actually I think they have been quite clear on what they meant by this as they have been very consistent in what they ask for.. you may not agree, and thats fine, but we know the ask...
They want all votes to be verified with a proper government issued photo ID in person. So no mail-in votes, and all states must require photo ID verified at the booths.
I personally dont like it because it breaks state sovereignty.. so I am against it. But I wont pretend I dont understand what they mean...
