So you are saying that Democratic voters will just "give up" if they were to "forget" their photo ID? That's silly logic.
If voting were that important to a person, "never have the time" is certainly not an excuse for not obtaining photo identification, any more than it would be an excuse for someone to file for food stamps. And if you want to vote, you "need" to get a photo ID. Pretty simple.
More than likely the people you describe to make your case have a really good reason to _not_ get a state issued ID or cannot obtain one for a variety of reasons.
