In American Samoa, the unseating of congressman Faleomavaega Eni Hunkin is being put down to his deteriorating health and a strong campaign by one of his opponents.
Unofficial results in yesterday's voting gave Aumua Amata 42 percent of the vote compared to the incumbent's 31 percent.
Our correspondent in Pago Pago Monica Miller says Aumua Amata has been trying for the seat for 20 years.
"Certainly Aumua Amata is no stranger to Washington. She has been serving on several advisory commissions relating to Asian Americans and Pacific Islanders. Definitely she has the contacts that would carry very well for American Samoa in Washington DC."
