White House hopeful Barack Obama has won his party's primary for Democrats living outside the United States, the Democrats Abroad organisation said on Thursday.
Obama won 65.6 per cent of the vote taken between February 5-12 in 164 countries and territories around the world, including Antarctica, compared to 32.7 per cent for his rival Hillary Clinton.
The global primary gives Obama his 11th victory over Clinton, although only seven delegates were at stake.
Obama has won 2.5 international delegates so far with two going to the former first lady, Democrats Abroad said. The remaining 2.5 votes will be determined at the Democrats Abroad Global Convention in Vancouver, Canada, on April 12-13.
"With the US image so badly damaged by the present Administration, American Democrats living overseas were eager to have their voices heard," said Christine Schon Marques, International Chair of Democrats Abroad in Geneva.
Democrats voted online for the first time in 164 countries, allowing a researcher at the US scientific mission at McMurdo Station, Antarctica, to cast her vote.
"The online Democrats Abroad Global Primary expanded the frontier of voting opportunities, and it works easily, even from the harshest continent on Earth," Lutchansky said in a statement released by Democrats Abroad.
