As millions of Americans head to the polls today, expatriates living in Ireland also have the opportunity to vote for their presidential candidate.
One of Dublin's most famous pubs, O'Neills of Suffolk Street, is hosting a ballot as part of the Global Democratic Primary, which will help decide the fate of Hillary Clinton and Barack Obama.
Kevin Lyda, a member of Democrats Abroad Ireland and one of the organisers, said the battle to be able to vote the first woman or black US president is so close it could be won or lost in Dublin.
"The next US president could be decided by someone in this pub," said Mr Lyda. "I know it sounds absolutely insane, but it's actually true. Any other election year that would not be true."
The O'Neills ballot is among polls of registered Democrats in more than 30 countries outside the United States that will help decide the party's candidate for George W Bush's successor.
The Global Democratic Primary allows all party members living abroad to cast their votes on "Super Tuesday," when more than 20 states hold contests. There will be 22 delegates returned from the global poll, each with half a vote, in the Democratic National Convention in August.
That convention will decide the party's White House candidate to run against the Republican candidate in the main election in November.
"Twenty two delegates out of 3,700 odd seems like a drop in the ocean, but it's not," said Mr Lyda, who grew up in Kansas and New York before emigrating to Ireland in 1998.
