Americans may still be undecided, but the rest of the world has made up its mind about who should be elected president of the United States.
A Gallup poll of 70 countries conducted from May through September has found widespread international support for Democratic candidate Barack Obama.
Around the world, respondents favoured Mr. Obama 4 to 1 over Republican John McCain.
In Canada, 67 per cent chose Mr. Obama and 22 per cent Mr. McCain. And 75 per cent of Canadian respondents said the presidential election would make a difference for their own country.
The Democratic nominee also enjoyed levels of support higher than 60 per cent in Australia, Germany, England and Japan, where the U.S. election was viewed as having a global impact.
Around the world, only Georgia, Cambodia, Laos and the Philippines backed the Republican candidate.
Europeans were the most likely to state a preference in the election and to believe the winner would have an impact on their own countries.
Mr. Obama also received an overseas endorsement Tuesday from the Conservative mayor of London, Boris Johnson.
"He visibly incarnates change and hope, at a time when America desperately needs both," Mr. Johnson wrote in the Daily Telegraph.
Within the United States, change seemed to be the theme of this week's polls.
A Pew Research Center poll released Tuesday found that the Democrat is enjoying his widest margin yet over Mr. McCain among registered voters, at 52 per cent to 38 per cent.
The Rasmussen Report, however, released a daily tracking poll that had Mr. Obama ahead by just four points, leading Mr. McCain 50 per cent to 46 per cent, and Gallup had Mr. Obama ahead 52 per cent to 41 per cent.
But attention is increasingly settling on key battleground states, where the two candidates are competing for the electoral votes they need to win the White House on Nov. 4.
Polls on Tuesday showed the Democrats leading in all of the battleground states won by John Kerry in 2004 and several won by Republican President George W. Bush.
A CNN poll Tuesday had Mr. Obama leading in Colorado by a margin of 51 to 47 per cent. In Florida, he was ahead 49 to 45, within the poll's margin of error.
The same poll found Mr. McCain leading in Indiana 51 per cent to 46 per cent, and in Georgia 53 per cent to 45 per cent.
It was reported this week that the McCain campaign had effectively given up on Colorado, Iowa and New Mexico, states the party had once believed would lead them to victory.
But Jill Hazelbaker, Mr. McCain's national communications director, released a statement Tuesday denying the report.
"We see the race tightening both internally and in public polling," she said. "We are within striking distance in the key battleground states we need to win."
