Republican Donald Trump says he won’t make a fourth consecutive bid for the US presidency if he loses the November 5 election, saying “that will be it”.

Asked if he saw himself running again in four years if he fails in his third consecutive bid for the White House, the 78-year-old former president told Sharyl Attkisson’s Full Measure program on Sunday: “No I don’t. I think that will be … that will be it. I don’t see that at all. Hopefully, we will be successful.”

Trump faces a tight race against Democratic US Vice President Kamala Harris.

Polls show the two neck and neck in key battleground states that are likely to be decisive in determining the winner, even as Harris begins to edge ahead in nationwide polls.

Trump launched his first re-election bid for the 2020 election the same day he was inaugurated in 2017 and announced his latest White House bid two years ago in November 2022.

He has continued to falsely blame his 2020 loss to Democratic President Joe Biden on widespread voter fraud and faces federal and state criminal charges over efforts to overturn the election results.

He denies any wrongdoing and has cast his indictments as a political attack against him while embracing increasingly dystopian rhetoric if he were to lose in 2024.

He has also launched businesses ventures amid his latest campaign, including Trump Media, NFTs and Trump-branded sneakers, coins and crypto.

Trump will be 82 by the 2028 election – a year older than Biden is now. The US President withdrew from the election race in July amid concerns about his health and advancing age.

Biden’s withdrawal makes Trump the oldest presidential election candidate in US history.

His rival, Harris, 59, has cast the election as a critical moment for US democracy even as she seeks to focus on kitchen-table issues such as costs for families and housing.

Asked whether the four-year break helped him regroup and figure out who he could trust as allies, Trump said: “It would have been easier if I did it … contiguous”.

“But the benefit is more than anything else, it shows how bad they were,” he said.

Trump, who spoke with Attkisson at his Florida resort, also said it was “too early” to make deals with people for any position in his White House cabinet should he win in November.
