Presidents are constitutionally barred from running for a third term under the 22nd Amendment, which states, “No person shall be elected to the office of the President more than twice.” But nothing stops someone from seeking second terms at any point, even after a re-election loss, meaning the answer to the question “Can Trump run again in 2024?” is yes. So if Donald Trump loses the 2020 presidential election, nothing stops him from running again in four years. And age wouldn’t necessarily be a factor. Trump would be 78 years old on the next presidential Election Day — roughly the same age as Joe Biden, who turns 78 at the end of this month.
