Voter turnout in the US presidential election is expected to be as high as 60%, with some states expecting over 70% of citizens to cast their ballots.
On the last day of campaigning before tomorrow’s election, the latest polls suggest that the US President, George W Bush, and the Democratic challenger, Senator John Kerry, are virtually neck and neck.
The candidates have been wrapping up their campaigns in the handful of states where just a few votes could make the difference between victory and defeat.
Mr Kerry today ends his campaign in Michigan, Wisconsin and Ohio. Mr Bush's final day of the campaign will be spent in six states before returning home to Texas.
Thousands of lawyers are standing by at polling stations to prevent fraud or unfair voting practices.
The two were deadlocked at 48% in the latest three-day national tracking poll, which included one day of polling taken after the airing of a videotape from al-Qaeda leader Osama bin Laden.
Mr Kerry led his rival 47% to 46% on Saturday with only 2% of voters still undecided.
