On the high cost of the lawsuit:

DOJ fought us every step of the way, prolonging the process and driving up costs… Had DOJ granted pre-clearance at the outset, as my office requested, it would only have cost the price of a postage stamp to mail a copy of the law to Washington. Instead, DOJ’s actions cost the citizens of South Carolina approximately $3.5 million. Why did the editorial not place the blame for the excessive cost where it rightfully belongs – at the DOJ’s feet?

On the facts of the case:

The editorial also misstated a key fact. It said, “In October, a three-judge panel upheld the law, but only if the state allowed voters to opt out of the photo ID requirement by signing an affidavit that they had a ‘reasonable impediment’ to getting a photo ID.” This is categorically wrong… The ‘reasonable impediment’ provision was in the voter ID law all along and was not added later by the judges or anyone else.

Looks like the Herald got it as wrong as DOJ did.
