A longer list not based on consensus might include Thomas Jefferson’s first term, Andrew Jackson’s two terms, Woodrow Wilson’s first term, Harry Truman’s two terms, and Ronald Reagan’s two terms. Of the consensus choices, all enjoyed a united government (in George Washington’s days, there were not really parties)."
