Minnesota and Wisconsin voters have, including those in Golden Valley, until 8 p.m. to cast their Election 2012 ballots, but voting in other key states ends as much as two hours before then, and exit polling could provide an early indication of whether President Obama or Mitt Romney wins the White House.

The earliest key state to watch for is Virginia, where polls close at 6 p.m. Minnesota time. 

Voting ends 30 minutes later in swing states Ohio and North Carolina. At 7 p.m. swing states Florida, Pennsylvania and New Hampshire close their polls.

Nevada and Iowa, which could be pivotal swing states, close voting at 9 p.m.
