Final answer:
More people voted in Andrew Jackson’s election than in Thomas Jefferson’s election primarily due to the establishment of A) universal manhood suffrage which expanded voting rights to more men, including those without property.
Step-by-step explanation:
The reason why more people voted in Andrew Jackson’s election than in Thomas Jefferson’s election can be attributed to the expansion of suffrage.
By the time of Jackson's presidency, suffrage was granted to more men, enlarging the electorate, or the body of people allowed to vote.
This era saw the end of property requirements for voting in many states, leading to universal manhood suffrage, which allowed a greater portion of the population, specifically white males, to vote, regardless of land ownership or social status.
Furthermore, Andrew Jackson’s election benefited from a stronger political party system and the portrayal of Jackson as a champion of the “common man” and a defender of states' rights, which helped him gain widespread support.
This appeal, combined with the end of the age of deference, led to a surge in popular participation in the election process. Therefore, the correct answer to why more people voted in Andrew Jackson’s election than in Thomas Jefferson’s election is A) Universal suffrage.
