Washington, 6 March

US President Joe Biden from the Democratic Party and his Republican predecessor Donald Trump have swept in their parties' presidential nomination primaries held in 15 states across the country, paving the way for a rematch between them in November and putting pressure on Indian-American candidate Nikki Haley to quit.

After Super Tuesday’s election results, Trump, 77, is hoping to establish a commanding lead in the delegate count and vanquish his only Republican opponent, Haley. Seeking his re-election, Biden, 81, swept almost all the Democratic primary states. He lost to Jason Palmer in American Samoa.

“Joe Biden isn’t facing any major competition in the primary cycle, and has won all the Democratic contests so far tonight, CNN projects, as he gears up for a likely rematch with Trump in November,” CNN said. Haley, 52, the former US envoy to the UN failed to make a mark Tuesday even as she showed strong support in the states of Vermont, where she won. That victory, however, will do little to dent Trump's primary dominance.

Trump prevailed in most of the Super Tuesday states: California, Texas, North Carolina, Tennessee, Alabama, Virginia, Oklahoma, Arkansas, Massachusetts, Utah, Minnesota, Colorado, Arkansas and Maine.

Super Tuesday is an important phase of presidential primaries when the early contests are over, and voters from multiple states cast ballots in primaries timed to occur on the same date. Almost all the results were one-sided in favour of Trump except for Vermont, where the winning difference was about one per cent.

More than a third of all the Republican delegates were at stake on Super Tuesday, the biggest haul of any date on the primary calendar. To win the presidential nomination of the Republican party, either of the two candidates needs 1,215 delegates, who are elected during the primaries. Before Super Tuesday, Trump had 244 delegates in his kitty, while Haley had 43.

Speaking from Palm Beach, Florida, Trump claimed that "we have a very divided country," and vowed to unify it soon. “This was an amazing night and an amazing day, it’s been an incredible period of time in our country’s history,” Trump said at his election night watch party at his Mar-a-Lago resort in Palm Beach. "We have a very divided country. We have a country [where] a political person uses weaponisation against his political opponents," he said.

He compared the state of the US political system to "third-world countries". "Never happened here. It happens in other countries, but they're third-world countries. And in some ways, we're a third-world country."

Talking up some of his achievements from his time in office, notably the half-built border wall between the US and Mexico, Trump claimed he delivered "the safest borders in the history of our country" and went on to rail against what he described as "migrant crime", without citing any evidence. "And so the world is laughing at us, the world is taking advantage of us," he said.

He goes on to describe his aims to make the US "energy independent and energy dominant". "All the … tragedy, you will not have to think of it. All of the problems we have today, we would not have had any of them," he said. "You would only have success and that is what ultimately going to unify this country and unify this party," he added.

Earlier, Biden touted the work his administration has accomplished in its first term in office while issuing a stark warning that a second Trump term would mean a return to "chaos, division, and darkness." "Four years ago, I ran because of the existential threat Donald Trump posed to the America we all believe in," Biden wrote in a statement, highlighting progress under his administration on jobs, inflation, prescription drug prices, and gun control.
