National Convention System of nominating presidential candidates.~Trollerton
The system the convention set up for choosing President was the electoral college.
national conventions for nominating presidential candidates.
The national convention system for nominating presidential candidates was developed by the Democratic Party in the early 19th century. This system was established to provide a more formal and inclusive process for selecting candidates, allowing party members from different states to come together and choose their nominee. The convention system has since been adopted by other political parties in the United States.
The nominating conventions used to be the place where the candidates were chosen. Nowadays primary elections often have the candidate chosen before the convention is held. However, if the primaries ended without any one candidates having a majority of the delegates in his camp, the convention would make the choice.
