First, let's not panic. SCOTUS upheld the most important part of the Voting Rights Act, which is federal review. What they overturned is the "map" of which states and jurisdictions must submit changes to federal review.
So let's draw a new map. What parts of the country are currently under voting rights assault from ALEC? What parts of the country could use a little federal voting rights protection from voter-ID nonsense, eliminating early voting nonsense, reducing polling places nonsense, all spawned by anti-voting conservatives, afraid of all those brown people casting ballots?
All fifty states. That's who.
So let's float a bill that extends the "map" to the whole country, which certainly would pass any judicial review. Let's make sure the bill comes up for a vote just before election, and let's make sure to brand it as the bill that will restore the 1964 Voting Rights Act.
And let's see how many Republicans have the gall to vote against a bill that makes things fairer for the whole country. And how big of a club we can beat them with in the next election.
Scalia thinks he's won. ALEC think they've won. But maybe they've just shot themselves in the foot.
