I guess it depends on how literal "all hell will break loose" is defined :). It was worth a story in the news, which is significant. How many of those does it take before it becomes a national headline? Way before we get to enough votes to matter. Imagine in either location it was, say, a dozen people saying that? There'd be calls to invalidate the election results in those areas and redo.

From the second link:

> North Carolina State Board of Elections data shows more than 2,600 voters cast provisional ballots during early voting this year. Around 19% of ballots cast were due to voters--like Prince--who were told they already voted.
