US President Joe Biden and his predecessor Donald Trump swept to victory in statewide nominating contests across the country on Tuesday, setting up a historic rematch in November's presidential election, though Nikki Haley's surprise victory in Vermont denied Trump a clean sweep of states in the race for the Republican nomination.
- The Super Tuesday primaries are the largest voting day of the year outside of the November general election. Elections are held in 15 states and one territory – from Alaska and California to Vermont and Virginia. Hundreds of delegates are at stake in the primaries, the biggest haul for either party on any single day.
- As expected, longtime frontrunner for the Republican nomination Donald Trump solidly beat his sole remaining opponent Nikki Haley, winning 12 of the first 13 states called, including the key swing state of North Carolina.
- Nikki Haley won the primary in the liberal state of Vermont, blocking Donald Trump from a clean sweep of victories. Haley had also won the capital Washington DC during the weekend, but is far behind Trump and is facing calls to drop out of the race.
- On the Democrats' side, President Joe Biden swept to victory in statewide nominating contests across the country. The only contest Biden lost Tuesday was the Democratic caucus in American Samoa, a tiny US territory in the South Pacific Ocean. Biden was defeated by previously unknown candidate Jason Palmer, 51 votes to 40.
