BigGov has more on the statistical foundation for the South Carolina Voter ID objection. This will not be good news for Section 5 when the Supreme Court gets a peek inside what the basis of this Section 5 objection was.  From Lee Stranahan:

What if the numbers of voters with no DMV-issued ID was REALLY small? Let’s say we discovered that the number of blacks with no DMV-issued ID was 1.4% but the number of whites with no DMV-issued ID was 1%. Now we’re down to a .4% difference and only dealing with a very small slice of the population. It doesn’t matter, thanks to the miracle of Holder Math!
