One excuse in that article is that some young-adult minorities may be college students and not have driver's licenses. If they are college students and don't have the means to procure a driver's license, then they are likely students at a public school and should thus have a student id from their public college - which is not therefore a state-issued photo ID?
A public school receives government funds and is "administered" by the government, but it's not quite what you would call a government agency. Look at small community colleges. Do you think they have the resources to produce a photo ID to the same standards as the government requires for prevention of counterfeits?
Yeah, our public school system could be improved so that it becomes a source of government issued IDs. So could post offices. But the point is that, right now, that's not the case. Even if it were, those cracker ass cake eaters at private schools would be disenfranchised. Do you know how hard it is to get their daddy's limo driver to take them to the DMV?
In addition to the above, you have to consider what the requirements are of public and private schools for obtaining a student ID. Would you need a photo ID for your application to enroll? Would you need it to get the student ID? Would FAFSA require it? Would private financial institutions that offer student loans require it?
I get that the vast majority of people have photo IDs. I also get that many people who don't have them can get off their lazy asses and go get them.
But for those who can't legitimately get a photo ID for whatever reason...do we disenfranchise them just because they are in a very small minority?
If you believe in nothing but a true democracy in which the majority always wins, then yes, we prevent them from voting just to make the majority's lives easier. But if you believe that the law should afford people certain basic rights, and that infringement on those rights should be avoided, then I think you have to consider their plight.
