That's mainly a joke, but this isn't:
... I anticipate that South Carolina (and Texas) will take the preclearance decisions to a three judge court in DC, with direct appeal to the U.S. Supreme Court. I further expect that in this litigation, South Carolina (and Texas) will argue, among other arguments, that Section 5 of the Voting Rights Act is unconstitutional...If review is expedited — which seems likely — the Supreme Court will be looking at this question and perhaps striking down the provision during the 2012 campaigns. Which party would be helped by that issue? Democrats will be positioned to preen about their concern for racial equality, and that puts Republicans in the position of championing the importance of leaving states alone to do things their own way, which — for some people at least — is a reminder of the bad old days when there clearly was discrimination and some states — mainly the states that are now stuck with the preclearance procedure — pontificated about "states' rights."
Nevertheless, I think the Republicans will be better off if this becomes an issue. First, people who reflexively impose that "bad old days" template are probably already voting for Democrats. Second, huge majorities of Americans support voter ID requirements, which means that few people buy into the race pandering. Third, playing the race card backfires once people clearly see that's all that's going on. And fourth, there really is something screwy about treating a few states differently from the other states, and if if a high-profile Supreme Court case makes people notice this strangeness, they'll be suspicious of the politicians and lawyers who strain to make the argument that it's right.
