Yes, he has. Only Grover Cleveland has served two non-consecutive terms as president in US history, serving his first from 1885 through 1889 and his second from 1893 to 1897.Despite the fact that Trump just obtained the second largest number of votes for a presidential candidate in US history, he has one significant barrier to overcome if he is to be re-nominated by his party.In June of 2024, when Trump will be 78 years old, he'll still be in his prime. That would make him the oldest major-party presidential candidate in US history, placing him on track to become the world's oldest leader at age 83 when his potential second term expires.In addition, by a similar measure, Trump had more supporters for his opponent than any other incumbent in US history. That's another reason why the GOP may consider alternatives in 2024.Mike Pence, Nikki Haley, and Ivanka Trump are the top pick for the Republican Party's presidential candidate in 2024, according to Endeavor Insights. It'll be the first time that a woman has run for president from either party. Ivanka Trump would be the first presidential daughter to receive such an offer.
