We have similar problems at the library, though our risk is merely financial. I consider voter fraud much more serious than theft of library materials. Unless we're talkin' Gutenburg. And even then...

We use any of the following to issue a library card: a current driver's license, with address correction issued by the state when pertinent; a Photo ID card issued by the PA Dept of Transportation (driver's license equivalent); passport or student ID with utility bill, lease agreement, or another official document with an identifying address; out-of-state driver's license or ID card-equivalent with official document indicating local address. The key is picture ID.

(For high school students, who can get their own cards at 14, we accept school ID for local kids and out-of-district school ID with working papers for those few new kids with no local school ID yet. Or their parent's ID. But since voters are all 18 or over, that wouldn't matter.)

The problem is, not all states' application procedures for driver's licenses are very strict from a security standpoint. The Feds can't walk in and demand the states all run their Depts of Transportation to the Feds' standards.

I think -- this pains me -- a national ID card is the easiest, most secure and most consistent answer. It reminds me enough of the internal passport to make me squirm, and we would have to give up some anonymity, but we've lost that much privacy anyway if we look at the world we live in honestly. I don't know if I would go as far as including fingerprints or retinal scans on them, though. Just because that gives me the creeps.
