US President Joe Biden and his predecessor Donald Trump swept to victory in statewide nomination contests on Tuesday, setting up a historic rematch in November’s election.
On a day traditionally dubbed Super Tuesday – when the most states choose who they think should be candidates – both virtually secured the nomination from their respective parties.
Republican Mr Trump won in Alabama, Arkansas, California, Colorado, Maine, Massachusetts, North Carolina, Oklahoma, Tennessee, Texas, Minnesota and Virginia, brushing aside Nikki Haley, who only won Vermont.
Meanwhile, Mr Biden appeared to win easily in 14 states but faced a sizeable protest vote in Minnesota where he still won. He lost in the US territory of American Samoa.
Despite their clear victories, a rematch between Mr Trump, 77, and Mr Biden, 81 – the first repeat US presidential matchup since 1956 – is one few Americans seem to want, based on opinion polls.
Speaking to a crowd gathered at his Mar-a-Lago home in Florida, Mr Trump described the president as the “worst” the country has ever seen.
“There’s never been anything like what’s happening to our country,” he added, before wrongly adding 15 million people have crossed the southern border from Mexico to the US.
But Mr Biden warned his rival – who is facing a litany of criminal charges, including interference in the 2020 election – is “determined to destroy our democracy”.
“He is driven by grievance and grift, focused on his own revenge and retribution, not the American people,” he said.
“He is determined to destroy our democracy, rip away fundamental freedoms like the ability for women to make their own healthcare decisions, and pass another round of billions of dollars in tax cuts for the wealthy – and he’ll do or say anything to put himself in power.”

How does the US election work?
Ms Haley, Mr Trump’s last remaining Republican rival, appeared to suggest she will carry on campaigning despite now having no viable route to the nomination.
“In state after state, there remains a large block of Republican primary voters who are expressing deep concerns about Donald Trump,” her campaign team said.
“That is not the unity our party needs for success. Addressing those voters’ concerns will make the Republican Party and America better.”
Immigration and the economy are leading concerns for voters in both parties, Edison exit polls in California, North Carolina and Virginia suggest.

A majority of Republican voters in those states said they backed deporting illegal immigrants, with Mr Trump promising to mount the largest deportation effort in US history if elected.
This year’s Super Tuesday has been dominated by two front-runners, which is unusual for a day that usually whittles down a pack to a few.
While Mr Trump and Mr Biden are almost certain to be the candidates, not enough states will have voted until later this month for either to formally become nominees.
