I'm having a lot of trouble finding what forms of ID the law blocked; could you point me to your source or identify what those forms of ID were? Even one or two examples will help if you don't remember everything.
Here's one. Acceptable IDs were "driver licenses, special ID cards, passports, veteran identification cards, military identification cards, tribal identification cards, and driver’s licenses from other states for voters who registered within three months of the election".
Not included, student IDs, government employee identification cards, and non-photo IDs.
What I have found so far is that they:
—eliminated same-day registration after determining African Americans benefited disproportionately from that service;
—eliminated high school pre-registration and pre-registration while obtaining a driver's license after determining African Americans benefited disproportionately from those services;
—shortened the early voting period from 17 days to 10 days after determining African Americans voted disproportionately during that period of time; and
—eliminated out-of-precinct provisional ballots after determining African Americans benefited disproportionately from that service.
You have not found any of those things. You have found opinions that this is what happened and why they did it.
Now, it is not entirely inconceivable that African Americans in North Carolina benefit disproportionately from every service that makes it easier to vote; and that a voting law that curtailed registration and tightened voting-day requirements would therefore necessarily disproportionately affect them; however, the answer to that suggestion depends on facts that I have not been able to obtain.
It would appear to be the conclusion everywhere. It's the old joke. The Washington Post headline: "God says world to end tomorrow; women and minorities hardest hit."
But, by all means, show me an example of a voting law being tightened up in the slightest without accompanying claims of suppressing minority votes.
