Residents of two tiny villages in northern New Hampshire headed to the polls at midnight on Monday, casting the first Election Day votes in the US.
After 43 seconds of voting, President Barack Obama and Republican Mitt Romney each had 5 votes in Dixville Notch. In Hart's Location, Obama had won with 23 votes, Romney received 9 and Libertarian Gary Johnson received 1 vote. Thirty-three votes were cast in 5 minutes, 42 seconds.
The towns have been enjoying their first-vote status since 1948 and it's a matter of pride to get everyone to the polls.
Before the polling booths opened President Barack Obama and Mitt Romney has raced from one battleground state to another in the final day of campaigning before Election Day, trying to fire up core supporters with an emphasis on the high-stakes choice between two contrasting visions for the future of the US.
Nationwide polls show the two locked in one of the closest, and most expensive, presidential races in recent US history. The hard-fought contest has laid bare one of the most polarised American electorates in decades choosing between very different paths for the world's most powerful country. Uncertainty over the outcome weighed on investors worldwide.
The incumbent Democratic president and his Republican challenger highlighted their sharp disagreements on the role of government in fixing problems from a stubbornly high unemployment rate to a one trillion US dollar-plus deficit. Amid a painfully slow recovery from the Great Recession, the economy is foremost on the minds of voters. The candidates' opposing views on other issues from gay marriage to abortion have added to the divisive atmosphere.
A majority of polls in the battleground states, especially in Ohio and other Midwestern states of Iowa and Wisconsin, show Mr Obama with a slight advantage. That gives him an easier path to the 270 electoral votes needed for victory.
Meanwhile, efforts are being made to help people in New York and New Jersey still facing multiple problems after Superstorm Sandy get to the polls. State officials have said that in counties declared emergency zones voters can fill out an affidavit ballot at any polling place they can reach.
Sandy killed more 100 people in 10 states but hit New Jersey and New York hardest. A week after the storm hit the mid-Atlantic and the North East, more than a million homes and businesses remain without power.
A spokeswoman said Obama will not campaign today, but remain in his home town of Chicago and reach out to swing-state voters through a series of television and radio interviews. Romney is campaigning in Ohio and Pennsylvania, before returning to his Boston home to wait for the returns.
