If there is a discrepancy between the VA Code and the regulatory definition, fix it. The point of driver's license expiration is not to indicate that you have ceased to be the same person; it's to indicate that you must periodically renew your license for driving purposes. I would prefer that voting-related identification not have an expiration date, or if it must have an expiration date for other reasons, that expiration date should not be considered for voter identification. There is no expiration of one's voting rights on the pure basis of time passing. Once you are old enough to vote, you will remain so, and there are already provisions for other changes (e.g. change of residency, death, criminal convictions).
