The large gathering of Democrats in Iowa was to shed more light on the identity of Donald Trump's future opponent in the November presidential election. But while the results of this first caucus were to be known the night of the vote, uncertainty still hovered on Tuesday.

The two candidates claimed the victory of the caucus. But official figures have yet to be released.
