What is the connection between Jacksonian Democracy and Majority Rule?
The very election of Andrew Jackson (1767-1845) in 1828 demonstrated that a "Champion of the Common Man" could attain the Presidency, winning an unheard of 60% of the Popular vote, and 70% of the Electoral College. "Jacksonian Democracy" was his brand of democracy that became embodied in the Democratic Party's platforms, characterized by the opposition of "special privileges" of the economic elites, the representation of farmers and wage earners, and the expansion into western lands.
The concept of Majority Rule, where the political and legal will of the majority is put in force over all opposition, may have served Jackson's and the Party's purpose in his election, and in parts of his political philosophy; however, it was applied inconsistently as a means of government, as exemplified by the Nullification Crisis in the 1832.
