Welcome to politics.co.uk's US election page. Here you'll find all the latest developments in the race on the other side of the Atlantic.
It's rare that politics.co.uk covers foreign elections at all, but this one will affect British politics in a way few others ever could.
America is involved in both the wars Britain is currently fighting. The country's response to the current financial chaos will help dictate its length and severity. And a change in America's attitude to environmental issues will have a strong impact on Britain and Europe's response to the issue.
But don't get too swept up with the presidential contest. There gubernatorial, senatorial and representative elections taking place as well. politics.co.uk will bring you the results of those as they come in.
We'll be covering the presidential run-off live with an As-It-Happens page throughout the night of the election, and we'll bring you all the latest news, features, comment, analysis and videos as the campaign builds to a climax.
