We all know that the decision aims to give states with a history of race based voter suppression more leeway to revert to their old ways. We also know that the decision was based on partisan interests, not law or justice. We can also be pretty sure that court had no business interfering in a Constitutionally irrelevant situation, just as they did in Bush v Gore.
And yet, the decision can be turned into a landmark moment for equal rights. There is no disagreement that Congress will have to do something about the struck down section of the VRA. It can weasel around and make something empty and pretty. Or it can move our voting disgrace one big step toward democracy. The way is simple, even elegant: when the issue comes up, forget about trying to reimpose the current restrictions on the wayward states. Instead make every single state subject to the same scrutiny when it tries to change its laws on who gets to vote. One person, one vote. That simple. It applies in Ohio and Michigan and Wisconsin and Illinois as much as it does to the South. It requires the funding to address and prosecute violators.
No discrimination, no "unfairness", no "singling out". Just enforcement of the Constitution for modern times.
I think this should become the focus of a huge push from Dems, liberals, leftists, and groups like MoveOn, Act Blue, DFA, etc. Make the Republicans/teabaggers defend blocking a nondiscriminatory act to follow what the Constitution demands. The Dems will need a big kick in the butt to get on this. We're the ones responsible for delivering it.
