Election Day projection

FINAL UPDATE: 22:32, 4 November 2008 (UTC)

• Data derived from Nate Silver's FiveThirtyEight.com weighted averages and statistical polling analysis, which determines what the best guess as to what will happen on Election Day is rather than what would happen if the election were held today. (Methodology)
• Each state is colored according to which candidate is currently projected to win, and both the state's total electoral votes and the winning candidate's projected margin of victory are listed.
• The actual result matches this map with the exceptions that Obama won Indiana and Nebraska's second congressional district.
