May 3, 2008: The Pacific island of Guam held its Democratic Party caucus. Barack Obama was victorious on the day, winning by a tiny margin of seven votes. Obama took 2,264 votes to Clinton's 2,257. This means of the four delegates up for grabs, Obama and Clinton take two apiece.
Guam residents have no vote in the presidential election but the tiny territory sends sends delegates to the Democratic convention in August.
Barack Obama led the delegate count by an estimated 1,733 to 1,598 in the delegate tally at the time of Guam's vote.
The island's vote was nestled between the Pennsylvania Primary (April 22) and 2008 Indiana Primary due to be held on May 6.
Despite the island's size, both Clinton and Obama ran TV ads on the island and took part in radio and phone interviews.
A village in Guam voted on April 26 because the caucus conflicted with a day honoring its patron saint.
