HAGATNA, Guam — Supporters of Hillary Rodham Clinton and Barack Obama are gathering at caucuses in Guam to pick among national convention delegates pledged to each of them.

Four regular delegate votes and two superdelegate positions are at stake at daylong polls Saturday at about 20 caucus sites around the island. The U.S. Pacific territory is 8,000 miles from Washington and a day ahead on the clock.

Party officials expected more than 3,000 voters to sign up as Democrats at community centers, schools, an old fire station and a village gym. It's a day of decision that usually passes without much notice in Washington.

This time, Obama and Clinton made their case for the territory's four regular delegates with local advertising and long-distance interviews.
