>but most states do not have a per se ID

Out of curiosity, do you have a source or list for this? My own home state and those around me that I've spot checked all have a state ID available as an alternative to a driver's license. My understanding was that this is the case for most states.

Unless I've misunderstood you and you meant a state ID that is completely separate from a driver's license to the point that people with a DL would have one?
