The US territory of American Samoa goes to the polls Tuesday to elect a new governor and House of Representatives -- but not for the US president.

Under the US constitution, residents of unincorporated territories such as American Samoa do not vote in US presidential elections, although they may do so in Democratic and Republican primaries.

Governor Togiola Tulafono and Lieutenant Governor Faoa Ipulasi Sunia are seeking a second term in office, despite the latter awaiting federal trial on charges of corruption, bribery and conspiracy to commit fraud.

He and another high-ranking official, Senator Tulifua Lam Yuen, are accused of using their official positions to influence cabinet members to illegally award their companies contracts for government work.

Three other pairings are contesting the joint-ticket posts of governor and lieutenant governor, promising to introduce more transparent and accountable government.

Around 17,000 people have registered to vote in the American Samoan poll. Because of its position near the dateline, voting starts at 1900 GMT Tuesday and concludes at 0700 GMT Wednesday.

As well as the governor and lieutenant governor posts, voters will select a non-voting delegate to the US House of Representatives and 20 members for the local House.

The non-voting delegate is unable to vote in the US House, but can vote in any committees they are a member of.
