Voting Rights Act in flux, new analysis needed

The Supreme Court of the United States recently ruled that the Voting Rights Act of 1965 needs updating. The list of states and jurisdictions that were covered by the VRA was deemed old and obsolete. So, now we need new analysis of where voting rights abuses are happening. Where is registration and turnout skewed indicating a systemic problem? Where are districts distorted by the gerrymandering tactics of cracking and packing? The temporary loss of VRA coverage may be a problem, but right now I'd like to be hopeful and optimistic that if we put some new consideration into this problem we can make things even better in the future.
