How did expanding democracy bring Andrew Jackson power?

Andrew Jackson was born on March 15, 1767 in Waxhaw, South Carolina. He was the 7th President of the United States who died on June 8, 1845. Jackson's efforts to limit the power of the affluent elite led to his reputation for 'Jacksonian Democracy.'
