Most states have some form of voter ID. Nine states currently require a photo ID. But it does no good to have it if you’ve got 30 million illegals from Latin America who have swamped our country and are going to be given amnesty: their voting will be the end of this country as we know it, whether or not they have photo IDs with them when they vote.
