Here's a question: The Voting Rights Act, including sections 4 & 5, was renewed by Congress in 2006 with sweeping majorities in both chambers. In fact, the vote was bipartisan in a manner that has only recently been reserved for acts authorizing the President to blow things up.

What has possibly changed in 7 years that warrants overturning very obvious will of the Legislative branch which has reviewed the very question of whether or not the formula in sections 4 & 5 needed to be changed?
