What are three things andrew jackson changed about the political system?

Unlike other famously strong Presidents, Jackson defined himself not by enacting a legislative program but by thwarting one. In eight years, Congress passed only one major law, the Indian Removal Act of 1830, at his behest. During this time Jackson vetoed twelve bills, more than his six predecessors combined. One of these was the first "pocket veto" in American history. The Maysville Road and Bank vetoes stood as enduring statements of his political philosophy.his controversial conduct in office galvanized opponents to organize the Whig party. Jackson devised and implemented his policies through a private coterie of advisers and publicists known as the "Kitchen Cabinet." His bold initiatives and domineering style caused opponents to call him King Andrew, and to take the name of Whigs to signify their opposition to executive tyranny.

Andrew Jackson changed the presidency by shifting the base of political power from its stronghold in the east to the western frontier of Tennessee. Also, unlike previous presidents, he did not defer to Congress in policy making, but used his party leadership and presidential veto to maintain absolute power hope this helps : )
