I am on the east coast. Polls here close at about nine, I suppose, with some variation based on state. It seems that the states that are both big and close (Pennsylvania, Florida, Ohio, and to a lesser extent Virginia) will all close at about the same time I guess.
If the election is close in those states, about what time will we be able to declare someone the winner in these states? If the election breaks more or less along the electoral college lines we now see, how soon will we know who has won the White House?
