Final answer:
The statement that voters choose delegates in a primary to represent them at a party convention is true. Delegates vote at the national convention to finalize the presidential nominee, and this is a key part of the nominating process in U.S. elections.
Step-by-step explanation:
In a primary, voters do indeed choose delegates who will represent them at a party convention; this statement is true. During primary elections, party members vote using a ballot to express their preference for a party's nominee. The delegates elected during these primaries then attend the national party convention, where they officially cast their votes for the presidential nominee. This is part of the nominating process where political parties determine who their nominee will be for the presidential election. The number of delegates each state sends to the national convention is based on the number of registered party voters in that state.
Additionally, delegates at the national convention make crucial decisions, such as finalizing the party platform and rules. They also rally support for the party's final presidential and vice-presidential nominees. This culminates the primary election season and kickstarts the general election campaign.
