Which of the following is a notable characteristic of Andrew Jackson's presidency?

The expansion of suffrage during Andrew Jackson's presidency is a notable characteristic because it marked a significant shift in American democracy. Jackson’s administration, which lasted from 1829 to 1837, is often associated with the promotion of the common man and increased participation in the political process. One of the key achievements of this era was the broadening of voting rights, particularly by reducing property requirements that had previously restricted voting to landowners. This democratization allowed more white males, including those who did not own property, to vote, thereby increasing political engagement and representation.

This movement towards expanding suffrage was part of a larger trend during the Jacksonian era that emphasized populism and the belief that government should be more responsive to the needs and concerns of the average citizen. It laid the groundwork for future reforms aimed at expanding voting rights to other groups in society. The other options, while historically significant, do not pertain to Jackson’s presidency. Focus on foreign affairs, the implementation of the New Deal, and the establishment of the Federal Reserve occurred outside of Jackson's time in office, making the expansion of suffrage the correct answer for this question.
