Super Tuesday, on March 5, is perhaps the most important day on the presidential nominating calendar, with the outcomes of races in 16 states and one territory poised to give virtually insurmountable delegate leads to both President Joe Biden and former President Donald Trump.
Headed into Super Tuesday, Trump has won nearly every GOP contest against his remaining major intraparty challenger, former UN ambassador Nikki Haley. The former president emerged victorious in key contests including the Iowa caucuses, New Hampshire primary, South Carolina primary, and Michigan primary, while Haley won her first primary in Washington, DC, on Sunday.
On Super Tuesday, Trump is looking to continue his dominant performance against Haley as he inches closer to earning the 1,215 requisite delegates needed to secure the GOP nomination. However, Haley continues to criticize Trump over everything from his electability to his judgment regarding foreign affairs, arguing that the GOP must turn the page from the former president.
Meanwhile, Biden easily won the early Democratic contests, but he encountered some pushback in last week's Michigan primary, when over 100,000 Democratic primary voters chose "uncommitted" to protest his refusal to call for a permanent cease-fire in Gaza. (He won the state's primary with 81% of the vote.)
Democratic challengers Dean Phillips and Marianne Williamson have so far attracted minimal support among the party's voters.
Here's a look at the states (and the territory) where voters will head to the polls on Super Tuesday:
