Who was the only president to serve split terms?

Answer 1

The first Democrat elected after the Civil War, Grover Cleveland was the only President to leave office only to return again four years later.

At 44, he emerged into a political prominence that carried him to the White House in three years. Running as a reformer, he was elected Mayor of Buffalo in 1881, and later, Governor of New York.

Cleveland won the Presidency with the combined support of Democrats and reform Republicans, the "Mugwumps," who disliked the record of his opponent James G. Blaine of Maine. A bachelor, Cleveland was ill at ease at first with all the comforts of the White House. "I must go to dinner," he wrote a friend, "but I wish it was to eat a pickled herring a Swiss cheese and a chop at Louis' instead of the French stuff I shall find." In June 1886 Cleveland married 21-year-old Frances Folsom; he was the only President married in the White House.

He therefore was the first to run for President and win twice and the first to marry while in the White House. :-)
