Answer:
His personal wealth.
Step-by-step explanation:
Before being elected as the president of United States, Andrew Jackson gained his popularity as a war Hero.
He was known for his contribution in war of 1812. During that time, he personally led 2,000 men to defend New Orleans from Great Britain's effort to occupy the territory.
He was never really known for his achievement in businesses. Most of his supporters perceive him as a masculine & charismatic leader who can defend United States from potential attacks in the future.
