DOJ not enforcing voting laws?

Over at NRO Corner is an article called "There really is something rotten in the Department of Justice." This matter is something that concerns us all as voters. Von Spakovsky says that a study reveals that certain states and the DOJ are simply not interested in removing dead voters from the rolls. Read it here:

This data shows some amazing results. For example, Adams says, there must be a fountain of youth in states such as Maryland, Arkansas, Massachusetts, Oregon, and Tennessee: None of them removed a single dead voter during that two-year reporting period. Many counties in states such as Alabama and Rhode Island also show a similar miracle — no voters were removed from their voter rolls for having died. If you have any ailing family members, these are obviously the states they should move to quickly. There are also several states — South Dakota, Mississippi, Texas, Kentucky, and Indiana among them — with more registered voters than (according to the Census) people of voting age.
