During Andrew Jackson's tenure, the congress-controlled caucuses were replaced by a more democratic system known as the "party convention." This shift allowed for broader participation in the nomination process, enabling party members and voters to have a greater say in selecting candidates. The move was part of Jackson's broader push for greater democracy and popular involvement in politics. This change laid the groundwork for the modern political party system in the United States.
