“What ACRU [the American Civil Rights Union] really has asked us to do is to rewrite the statute so as to treat all of the categories of ineligibility in the same way,” added Marcus, who was joined in the ruling by judges Britt Grant and Frank Hull. “It would have us read the statute as imposing on the states a general program of list maintenance that makes a reasonable effort to remove any ineligible voter, regardless of the basis of ineligibility. But we may not rewrite the unambiguous text, where Congress has been crystal clear in treating different categories of ineligibility in different ways.”
