Problems at the poll? Here's who to call

If you notice any voter fraud or intimidation, you can report the activity to the Department of Justice at 1-800-253-3931 or call the NAACP at 313-664-2424.

The Detroit Branch NAACP Voter Hotline is set up to assist voters with questions about where to vote and to report any signs of voter intimidation or suppression. The voter hotline will be available on Tuesday from 7 a.m. - 8 p.m., the same time the polls are open.

The Department of Justice also has 12 poll monitors in town to keep tabs on voting precincts in Detroit, Dearborn Heights and Hamtramck for voter fraud and intimidation.

"I've heard urban legends of people who will be waiting in line and somebody will walk up looking very official with a clipboard who might say, 'I hope everyone with child support has that paid off,'" US Attorney Barbara McQuade said. "That might cause someone to leave."

That is an example of voter intimidation.

"Examples of fraud might be somebody impersonating a deceased voter, someone who is bribing a voter, paying them to vote a certain way," she adds.

The consequences of that could be criminal prosecution with penalties including jail time.
