Where we always second guess!
John Adams (b. October 30, 1735 or October 19 according to the old-style calendar, d. July 4, 1826) was the second president of the United States of America, following George Washington’s 8 years in office. Adams, a Federalist from Massachusetts, was president from April 21, 1789 to March 4, 1797. He was elected president by the very narrow margin of 71 electoral votes to Thomas Jefferson’s 68. To round out the field, Thomas Pinkney had 59, and Aaron Burr won 30. As per the rules of electing presidents back then, Jefferson who received the second-most electoral votes served as Vice-President.
Adams served only one term before being defeated by Thomas Jefferson in the election of 1800.
