Jackson's presidency represented a turning point in U.S. political history and led to the emergence of the Democratic and National Republican (Whig) parties. In many ways, Jackson elevated the presidency to new levels of power and importance. In his first address to Congress, he suggested getting rid of the Electoral College (maybe because of his personal experience!). He used his veto power liberally, and often made policy without working with Congress.
Presidential candidates throughout the 19th century (and even today) often try to imitate his rise to power: humble beginnings, military heroism, and devotion to democracy. As the population of settlers expanded west, new states were admitted to the Union, and Jackson benefited from a growing sentiment of democracy surrounding the expansion. He was more popular when he left office than when he entered.
