NEW YORK (MarketWatch) -- Sen. Barack Obama headed to victory in the Guam Democratic Party caucus Saturday, leading his rival Sen. Hillary Clinton for the four pledged delegates at stake in the race for their party's nomination.

With 95% of the vote counted, according to a CNN tally, Obama had won 53% against Clinton's 47%, even as the two hopefuls were busy campaigning for the Indiana and North Carolina primaries slated for Tuesday.
