The linked article on list those people who do not have a id from the transportation department. Doesn't list the ;numbers that have the other kinds of id. And the law says people can get a free id from the department of transportation. So I don't see that they have any excuse for not voting.
I think it comes down to this... there will be a number of people who will be disenfranchised because of this this since they are unable to get to a DMV, don't know about the law, or whatever before the election. Yes, crazy, blah blah, I get it, but for some people it may not be the priority it is for us. Should these people get to vote this election? I think so. But, given adequate time, I think most people can get photo IDs.
It seems to me laws like this should be implemented for future elections(that is, not active for this November) they should take advantage of the upcoming election to spread the word about the policy change. that is, when you go to vote, they tell you the next election you WILL need a photo ID. If you don't have one, they should allow you to vote then immediately set you up with a way to get one. Obviously every polling place can't necessarily issue government IDs but provide information etc on how to get one, which will mean those individuals who right now vote without a photo ID will be explicitly informed of the change and given a whole hell of a lot of time, as well as help, in getting one.
