Grover Cleveland was a very special President. He was the First Democrat elected after the Civil War, and also was the only President to leave the White House and return for a second term four years later. In addition, in his second term, Grover Cleveland was the third of four presidents to win the popular vote but lose the election (the others: Andrew Jackson [1824]; Samuel Tilden [1876]; and Al Gore [2000]). He was also the only president married in the White House. The First Democrat elected after the Civil War, Grover Cleveland was the only President to leave the White House and return for a second term four years later. He also vetoed many private pension bills to Civil War veterans whose claims were fraudulent. When Congress, pressured by the Grand Army of the Republic, passed a bill granting pensions for disabilities not caused by military service, Cleveland vetoed it, too. He also signed the Interstate Commerce Act, the first law attempting Federal regulation of the railroads. In December 1887 he called on Congress to reduce high protective tariffs. Although Cleveland would not win the next election, he did, as mentioned before, come back, as the only President to leave the White House and return for a second term four years later.
