Now here is the kicker that undermines a lot of what this thread was saying. If Yankees are the anti-authority/rebellious/egalitarian ones, than why was the whole of the 19th century defined by a largely New England centered party that almost always sided with the elites, versus a party based in the South and west that was almost universally defined at its core of opposing the elites?
This didn't happened unless you mean the Greenback and Populist parties, yet you seem to speak of the Democratic Party. The Democratic Party simply favored Southern slave-agricultural elites and the Catholic heriarchy over Protestant clergy and Northern industrialists.
