It's not known yet exactly how many Michigan election precincts ran short of ballots during Tuesday's primary.
Secretary of State spokesman Fred Woodhams thinks it's a small number.
"Michigan has 4,800 precincts," Woodhams said. "At this point we're aware of a dozen or so precincts that ran low."
Woodhams said it's also not clear which party's ballots ran out.
"Anecdotally, it seems some precincts were low with Republican ballots, and other precincts were low with Democratic ballots," said Woodhams.
