When Will Presidential Election 2012 Results Be Announced in Ohio?

Ohio voters have until 7:30 p.m. to cast their ballots, but voting in other key swing states doesn't end until hours later. Exit polling could provide an early indication of whether President Barack Obama or Mitt Romney will win the White House.

The earliest key state to watch are Virginia and Florida, where polls close at 7 p.m. Voting also ends at 7:30 p.m. in fellow swing state North Carolina. The majority of New Hampshire's polls close between 7 and 8 p.m.

At 8 p.m., the swing state of Pennsylvania closes its polls. A portion of Florida closes its polls at 8 p.m. Eastern Standard time, too—the state is split across two time zones. 

Iowa and Nevada close voting at 10 p.m.

Politico has a full map of voting times across the country. The times above are all adjusted to Eastern Standard Time and verified with state websites.
