Here is an excerpt:
"Should it still be the law to require states and voting districts throughout the country (but mostly in the south) to seek approval from the Department of Justice before making changes to their election procedures?
Well, Congress has decided that it has. In 2006, Congress extended the portion of the 1965 Voting Rights Act that requires 'covered' jurisdictions to seek DOJ approval for another 25 years.
But was Congress’s decision to do that justified by the evidence?"
