WASHINGTON -- Gov. George W. Bush swept presidential contests in four U.S. territories over the weekend, walking away with more than two dozen Republican delegates to the national convention.

The victories increased the delegate total for Bush to 93 and narrowed the gap between him and John McCain, who has 96. A candidate needs 1,034 delegates to win the Republican nomination for president.

Bush easily defeated McCain during Sunday's primary in Puerto Rico to win all 14 delegates from the island. He also swept caucuses held a day earlier in Guam, American Samoa and the Virgin Islands, each of which had four delegates at stake.

In Puerto Rico, with 99 percent of the polling stations reporting, Bush received 89,448 votes, or 93 percent, and McCain had 5,647 votes, or about 6 percent. Former ambassador Alan Keyes and publisher Steve Forbes, who dropped out of the GOP race earlier this month, each received less than 1 percent of the vote.

While Bush picked up additional delegates, he cannot count on getting their votes in November if he wins the nomination. That's because residents of U.S. territories cannot vote in the general election, even though they may participate in presidential primaries and caucuses.

Still, Bush supporters called the victories significant, particularly after a pair of losses in primaries held in Arizona and Michigan.

"This is a tremendous triumph not only for Puerto Rico, but on the national level because it is the first group of Hispanic voters that has voted solidly with Governor Bush," said Jose Fuentes Agostini, the island's former Attorney General and co-chair of Bush's campaign.

During Saturday's contests, there was a motion to split Guam's four delegates between Bush and McCain, but a binding motion to support only Bush prevailed, said Fred Castro, the national committeeman-elect.

In the Virgin Islands, Republicans met on the Caribbean islands of St. Thomas, St. Croix and St. John, said the territory's GOP committeeman, Holland Redfield II. He refused to give a breakdown of how participants voted during the closed assemblies.
