Super Tuesday: everything you need to know as 16 states vote

Here's what to expect as 16 US states and one US territory will head to the polls to cast ballots in presidential primaries

Voters in 16 US states and one US territory will head to the polls on Tuesday to cast ballots in presidential primaries, as the country once again observes the quadrennial tradition of Super Tuesday".

In past election cycles, Super Tuesday has provided a clear indication of which candidates will win their parties' presidential nominations. In 2020, for example, Joe Biden brought Bernie Sanders' march to the Democratic nomination to a crashing halt after he won 10 of the Super Tuesday states. Biden went on to become the Democratic nominee and later won the general election against Donald Trump.
