Donald Trump has generated controversy after promising a gathering of fans that they "won't have to vote again" if he wins the president in November.

Speaking at a rally in Florida organized by the conservative group Turning Point Action, he exhorted Christians to "get out and vote," adding, "Just this time, you won't have to do it any more."

Mr Trump said that the vote would be "fixed" and that attendees "would no longer have to vote."

Critics of Mr Trump have expressed fear that his re-election could erode America's democratic institutions and lead to the politicisation of the civil service.

Mr. Trump continues to declare, without evidence, that the 2020 US presidential election was "rigged".

His words at the time helped spark a deadly insurgency.

In November last year, he told Fox News that he would be a “dictator on day one” if given a second term in the White House.

If Mr Trump wins a second term in the White House, he can serve only four more years as president under the constitution.

In May, speaking at a National Rifle Association gathering, Mr Trump joked about serving more than two terms as president.

He referred to the presidency of Franklin D. Roosevelt, a Democrat, the only president to serve more than two terms.

The two-term limit was added after Roosevelt's presidency.

"You know, FDR, 16 years - almost 16 years - he was four terms. I don't know, are we going to be considered three-term? Or two-term?" Mr Trump asked the NRA crowd.

Recent polls show that Mr Trump’s significant lead over Joe Biden has been erased since the President announced he would step aside, passing the torch to Kamala Harris.

Mr Trump plans to appear at a campaign rally on Saturday in Minnesota alongside his vice presidential running mate Senator JD Vance.

Harris, 59, will attend a private fundraiser on Saturday, after a series of campaign stops this week.

During his speech in Florida, Mr Trump described Mrs Harris as “a far-left bum” and a “failed vice president”.

Mrs Harris hit back hours later, calling Mr Trump someone “you wouldn’t want to sit near at a restaurant”.
