Biden Trump Haley
President Joe Biden, former President Donald Trump, and Nikki Haley, a former UN ambassador an ex-governor of South Carolina.
  • Both President Biden and former President Trump are focused on the November general election.
  • But they must first win over voters in a slew of primaries and caucuses on Super Tuesday.
  • Nikki Haley has continued to campaign vigorously against Trump in the GOP primary.

Super Tuesday is perhaps the most important day on the presidential-nominating calendar. This year, the outcomes of races in 16 states and one territory on March 5 are poised to give virtually insurmountable delegate leads to both President Joe Biden and former President Donald Trump.
