US General Elections

Electors are casting ballots for the gubernatorial race - to elect the governor and lieutenant governor; for the territory's Delegate to the US House of Representatives and 20 or the 21 members of the local House.

The Swains Island seat was already decided in a meeting last week, with incumbent Su'a Alexander Jennings returning for an eighth term.

Prior to polls open today 1,601 absentee ballots had already been. Of these, 892 are outside or off island absentee ballots and 709 are local absentee votes.

Two Democratic former US presidents, Bill Clinton and Jimmy Carter, and former Secretary of State Colin Powell, a Republican, endorsed Mr Biden.

Mr Clinton said President Donald Trump had brought "chaos" to the Oval Office.

Mr Trump trails Mr Biden in opinion polls ahead of November's election.

This is Mr Biden's third White House bid - his coronation as the Democratic nominee represents a remarkable turnaround given that his campaign appeared to be in danger of collapse in February.
