For there to be a “next time”, he’ll obviously need to run again.
Who else will seek the Republican nomination?
If Mr Trump does indeed run, there’s every chance no one of note will oppose him. That’s what happened in 2020.
But he was an incumbent president at that point, and incumbents rarely get challenged for their party’s nomination. This time might be different.
So who are the potential contenders?
Mr Pence, who served as Mr Trump’s loyal vice president for four years, might have a go – though he has fallen out of favour with many Republicans since he refused to unilaterally (and illegally) overturn Mr Trump’s defeat to Joe Biden.
Florida Governor Ron DeSantis would be an immediate top tier candidate, having won admiration among Republicans for his handling of the coronavirus, which focused on keeping the state’s economy as open and unrestricted as possible.
South Dakota Governor Kristi Noem was another leader sceptical of Covid restrictions, and she has a national profile.
Pro-Trump senators like Ted Cruz, Rand Paul and Josh Hawley have obvious presidential ambitions. Mr Cruz and Mr Paul ran against Mr Trump for the Republican nomination in 2016, and failed, though Mr Cruz did get second place.
Should Mr Trump stay out of the race, his son Donald Jr might think about a bid.
Both of these guys are notably old by historical standards. Mr Trump was the oldest president ever elected to a first term when he took office in 2016, edging out Ronald Reagan. Mr Biden is the oldest ever elected full stop.
Who would face Trump in the general election?
Mr Biden’s age is a factor here. He’ll be just a couple of weeks short of his 82nd birthday when the 2024 election is held, almost a decade older than Mr Reagan was when he won re-election in 1984.
The President insists he intends to run again.
“My plan is to run for re-election. That’s my expectation,” he said in March.
