The primary purpose of a party convention is to nominate candidates for president and vice president.

Party conventions are attended by delegates from each state, elected officials, party leaders, and other interested individuals.

Delegates to a party convention are selected by a combination of state party committees, primary elections, and caucuses.

Delegates to a party convention have the role of voting for the party's presidential and vice presidential nominees, adopting the party platform, and electing party leaders.

The process for nominating a presidential candidate at a party convention involves delegates from each state casting their votes for their preferred candidate, the candidate with the most votes winning the nomination, and if no candidate receives a majority of the votes, there is a second round of voting.

The process for adopting a party platform at a party convention involves a committee of delegates drafting a platform, the platform then being presented to the full convention for a vote, and the platform being adopted if it receives a majority of the votes.

The party platform serves to outline the party's positions on the issues, attract voters to the party, and help the party's candidates win elections.

There are three types of party conventions: national conventions, state conventions, and local conventions.

Party conventions are typically held in the summer before a presidential election.

Party conventions are typically held in a major city.

Party conventions typically last for three days.

Some of the activities that take place at a party convention include speeches by party leaders, musical performances, and fireworks displays.

Party conventions serve to unify the party, generate excitement for the upcoming election, and provide an opportunity for the party to showcase its candidates and platform.

Some of the challenges that party conventions face include the high cost of hosting a convention, the difficulty of managing a large number of delegates, and the potential for protests and demonstrations.

Party conventions have changed over time in that they have become more expensive, more media-focused, and more political.
