President Biden's bid to sweep the Super Tuesday primaries was undone by an unlikely challenger, far from the U.S. mainland. Jason Palmer, an under-the-radar candidate, edged Biden by just 11 votes in American Samoa, netting 51 ballots to the president's 40.

Palmer's campaign says American Samoa isn't the only place he's been campaigning in the Pacific.
