Zoom meetings and beach clean-ups: how unknown Jason Palmer upset Biden in the American Samoa primary

Residents of the US territory say a targeted ad campaign was responsible for the US president's loss in the Democratic Super Tuesday caucus

In less than 24 hours, Jason Palmer went from being a relatively unknown Baltimore businessman, to toppling a sitting president in a US primary caucus. Since then he's been featured in newspaper profiles, been interviewed on major news networks - and found himself the subject of internet memes across the world.

Joe Biden's campaign team may have expected to win every Democratic contest on Super Tuesday - but if so, they didn't account for American Samoa. Of the 91 ballots cast in the territory's caucus, Palmer won 51, while Biden received 40.
