Trump, 77, and Biden, 81, won in Arizona, Illinois, Kansas and Ohio on Tuesday. Trump also won the Republican primary in Florida, where the Democrats are not holding a primary. In Florida, Trump swept the Republican primary taking home all the 125 delegates

Indian-origin former South Carolina Governor Nikki Haley, who has now withdrawn from the race, got 14 per cent of the votes and Florida Governor Ron DeSantis received four per cent of the votes in a low turnout. DeSantis has also withdrawn from the race

"Trump demonstrated absolute dominance in the result. Polling for the general election shows that his dominance in Florida will continue until November. Florida is Trump Country," said Trump senior adviser Brian Hughes

In Arizona, Haley surprisingly received 20 per cent of the votes. Trump with 76.2 per cent of the votes bagged all the 43 delegates at stake. Arizona is considered to be a battleground state. Now Trump has 1,623 delegates and Biden has 2,483 delegates

In a rematch of 2020, Biden and Trump are facing each other in the November 5 presidential elections. After the Super Tuesday primaries on March 5, the two emerged as the presumptive nominee of the Republican party. Their rematch is expected to mirror the 2020 campaign, though Trump will run this time under the spectre of 91 felony charges

Trump is expected to become the first former American president to go on trial in a criminal case on March 25 in New York, where he faces charges he falsified business records to hide hush money payments to a porn star

Other charges are related to allegations that he plotted to overturn his 2020 election defeat to Biden; played a lead role in the January 6, 2021, insurrection at the US Capitol and illegally took classified documents from the White House. It would be the first presidential rematch since 1956

The last presidential rematch came in 1956 when Republican President Dwight D Eisenhower again defeated Adlai Stevenson, the Democratic opponent he had four years prior

Biden defeated Trump in the 2020 November elections, an outcome still challenged by the Republican leader. With the presidential nominating contests clinched, the candidates were focusing on campaigning in swing states they would need to win the general election in November
