Decision day dawns as voters in the US prepare to give their verdict on the two presidential candidates.
Barack Obama and John McCain have not wasted a minute in the final hours of the 2008 campaign, both undertook a whirlwind tour of states in the hope of grabbing that undecided voter.
Opinion polls still give Obama a lead with the Democrat taking a projected 291 electoral collage votes compared to Republican McCain’s 163.
Election officials are bracing themselves for the biggest voter turnout in US history, somewhere between 130 and 140 million.
Analysts are warning that if there are any hitches with the machinery of voting, there could be problems.
“The turnout is expected to be extremely high which means it is going stress the whole election system so something that could have been a small problem in a previous election could end up being a very big problem because as you are dealing with issues, the lines are growing longer and longer,” said Information Security Expert, Avi Rubin.
In the shadow of the 2004 election, this time high-tech voting is not available across all the states. Americans will today be casting their ballots using everything from computers to paper and ink.
