18th and 19th Century Presidential Eras

[Oldiesfreak1854]

Here's my theory:

Washington era (1789-1800): Washington and John Adams-- Federalists win 3 of 3 presidential elections due to Washington's popularity and status as a war hero; even despite not running in 1796, Federalists still manage to pull out a narrow win
Jeffersonian era (1800-1828): Jefferson through John Quincy Adams-- Democratic-Republicans win 7 of 7 presidential elections after the defeat of John Adams in a nasty campaign
Jacksonian era (1828-1860): Democrats win 6 of 8 presidential elections, starting with the defeat of an Adams in one of the dirtiest presidential campaigns to date (like Jeffersonian era)
Republican era (1860-1932): Lincoln through Hoover-- Republicans win
New Deal Democrat era (1932-1980): Roosevelt through Carter-- Democrats win 8 of 12 presidential elections due to the Great Depression and attacking Republicans as the "party of the rich" (which they still use with success)
Reagan era (1980-1992): Reagan and George H. W. Bush-- Republicans win 3 of 3 presidential elections due to Carter's unpopularity and incompetence in 1980
Clinton era (1992-present): Clinton through Obama-- Democrats win 4 of 6 presidential elections due to social issues alienating moderates with the GOP
