President Joe Biden and his predecessor, Republican Donald Trump, are looking to all but clinch their party’s nominations as both are heavily favored in each of the 16 states and one territory holding Super Tuesday primaries on March 5.

Super Tuesday, one of the biggest days in presidential primary campaigns, is here: President Joe Biden and former President Donald Trump could each get more than a third of the total delegates needed for a rematch in November. 

Fifteen states and one territory take part in Super Tuesday, the largest delegate haul of any day in the primary calendar. Neither Trump nor Biden will be able to claim the title of "presumptive nominee" – the earliest that could happen is March 12 for Trump and March 19 for Biden – but both could get pretty close.
