Both the international and U.S. delegations were invited by the Marcos government and Mrs. Aquino's campaign.

The commission computer workers, after leaving the tabulation center, drove across town to the Baclaran church, where several U.S. observers saw them after midnight.

"They are very frightened," said Sen. John Kerry, D-Mass., as a crowd gathered inside, cheering and clapping. "They are scared of retribution, scared of the government."

In Baclaran, Mrs. Aquino, 53, widow of assassinated opposition leader Benigno Aquino, appeared at Masses in her honor. She was greeted with cheers of "Long live the president" and "Cory, Cory, Cory," her nickname.

Other supporters staged a parade in the southern city of Davao.

"Despite all the cheating and violence, right will prevail," said Mrs. Aquino, who was escorted with the church by a wedge of private security guards. "We will pass through the barrage of lies to win this election."

A political novice who had spent recent years as a housewife, Mrs. Aquino entered politics after her husband, a former visiting professor at Harvard and Marcos' prime political opponent, was shot in 1983 upon returning from self-imposed exile to the Philippines.
