After Joe Biden defeated Donald Trump in both the popular vote and the Electoral College in the 2020 presidential election, the results were contested on many fronts.

In a campaign to overturn the election that became known as the "Big Lie," Trump and ardent supporters such as former New York City Mayor Rudy Giuliani impugned election workers, claimed massive voter fraud and called for recounts in states with relatively close margins.

And then there was the storming of the US Capitol on January 6, 2021, a last-ditch effort to overturn the election by force.

Trump is again the presidential candidate for the Republican Party in 2024. Along with many of his supporters, including his running mate, JD Vance, he continues to repeat the false claims about the 2020 election.

The Trump team has also refused to commit to accepting the outcome of the 2024 election, leading to fears of new upheaval in the US should he not be declared the winner.

A landslide victory for the Democratic nominee, Vice President Kamala Harris, would make significant challenges by mainstream Republicans less likely.

When it comes to accepting defeat, 72% of voters say Harris will accept the results, acknowledge Trump's victory if he wins and concede, according to survey results released by the Washington-based Pew Research Center on October 10.

The same survey found that only 24% think Trump will concede if he loses the election.

But the campaign to reinstall Trump as president started long before the polls, and there have been significant efforts to limit who can participate in this year's election.........
