I don't think it should just be a driver's license as proof to show you are who you say you are. You should be able to use a passport, your job photo badge if you have one, a college ID card, some type of card that has your info and photo on it, etc...
Are you going to tell me that people can't get that ? And aren't you a racist when you say that minorities shouldn't have to show ID when they vote because you say they usually can't get it? With your logic, you're implying that every person from a minority group is helpless, stupid, and cannot do simple things on their own. What does that say about you?
And again, if I don't have to show my ID to vote then why should I have to show it if I want to buy alcohol and tobacco? You're picking and choosing.
