Hillary Clinton will become the second presidential nominee to win the popular vote yet lose the electoral college – and thus the White House – in the past five US presidential elections. It would be the fifth time in the nation’s history that such a split has occurred and may be a boon to advocates of reform of the two-century-old system. Other dubious winners include Al Gore (George W Bush, 2000), Grover Cleveland (Benjamin Harrison, 1888), Samuel Tilden (Rutherford B. Hayes, 1876) and Andrew Jackson (John Quincy Adams, 1824).
