A. to assign delegates from each state to the national party convention

The presidential primary is a process where political parties in various states hold elections to choose delegates committed to voting for a particular candidate at the national party conventions. These conventions are where the parties officially nominate their candidates for President and Vice President of the United States. The primary system is integral to the nomination process and allows party members to have a say in who will represent them in the general election.
