I agree from the Court's perspective, but I don't see how this Congress could come to an agreement on a new formula. I could see Sect 5 with no covered jurisdictions as a result.
I agree. I don't think this Congress would update Section 4 so as to have an enforceable Section 5. However, that sort of calculus is pretty much irrelevant when it comes to the decision processes of the Supreme Court. As I mentioned before, the obsolescence of Section 4 is essentially the undoing of the VRA. I can see the constitutional arguments with it. I don't think Section 5 itself raises any constitutional issues. If Congress were to extend Section 5 to the entire country, I think it would perfectly consistent with the Constitution. The real issue seems to be the coverage formula, which I think the Court will strike down.
