Story highlights Hillary Clinton aides have been eying American Samoa as a symbolic victory over Bernie Sanders

On Tuesday afternoon Hillary Clinton called into American Samoa's sole caucus site to ask for voters' support in the Democratic primary

(CNN) With just six delegates at stake, American Samoa isn't the most significant caucus in the country. But senior Hillary Clinton aides have been eying it as a symbolic victory over Sanders.

The Vermont senator won big in New Hampshire, but he only secured six more delegates from Clinton in the Granite State.

Clinton's top aides hope to win all six American Samoa delegates -- and think they can -- wiping out Sanders' biggest victory of the campaign.

That's why Tuesday afternoon, Hillary Clinton called into American Samoa's sole caucus site to ask for voters' support in the Democratic primary.
