Explanation: The 1828 United States presidential election was the 11th quadrennial presidential election. It was held from Friday, October 31 to Tuesday, December 2, 1828. It featured a re-match of the 1824 election, as President John Quincy Adams of the National Republican Party faced Andrew Jackson of the Democratic Party.
