Sounds like Chesterfield County (just south of Richmond, VA) screwed things up badly enough in the February 12th presidential primary to draw a complaint at the Department of Justice:
The civil-rights complaint says hundreds of Chesterfield residents were deprived of the right to vote, primarily in precincts with the largest black populations. They allege that in nine of 63 precincts, county voting officials failed to provide enough Democratic ballots and told voters to cast ballots on blank scraps of paper, which weren’t counted.
A close-up view of the problem, written not long after the primary at hand, can be found here. Providing for elections is among the core (and most predictable) functions that government can provide. Any time a place screws it up this badly, it’s not unreasonable to wonder if it goes beyond incompetence.
