Who is the only President in U.S. history to be elected in two non-consecutive terms?

The only President in U.S. history to be elected in two non-consecutive terms is Grover Cleveland. He first served as the 22nd President from 1885 to 1889 and then returned to the presidency as the 24th President from 1893 to 1897. Cleveland's unique position in U.S. history is notable because it demonstrates how he managed to regain the presidency after having lost his re-election bid, which had not been achieved by any other president before or since. This historical fact emphasizes his resilience and appeal among voters, allowing him to leave a distinctive mark on American politics.
