If a mega-precinct is available, that means voters can cast their ballots on Election Day at any precinct in the jurisdiction, regardless of their home address. In addition, groups of people in the same jurisdiction who are friends or family but who don’t have the same voting location can vote together at a mega-precinct. Expenses on Election Day can be reduced with fewer locations to staff. There will be 19 NBA arenas turned into voting locations on Election Day, as well as the practice facility of the Detroit Pistons.
