Very citizen can obtain an I. D.
This I. D. can be matched up against their voter roll information.
I have no idea how this is discriminatory.
Whites, blacks, hispanics, asians, and everyone else can get an I. D. They can all present it when they vote.
This eliminates no one from participation, as long as they produce and I. D.
Is it not possible to photograph them when they vote, and create the ID on the spot. check them against face recognition software after the vote, and arrest them if they voted twice?
