One of the main roles of political parties is nominating candidates. This process involves selecting individuals to represent the party in elections, such as presidential, congressional, or local races. Political parties play a crucial role in identifying and endorsing candidates who align with their ideologies and policy priorities.

By nominating candidates, political parties give voters a clear choice between different platforms and visions for governance. This process helps shape the political landscape and influences the direction of public policy.

While voting is essential for the functioning of democracy, it is not a role of political parties themselves. Making commercials is a tactic used by parties to promote their candidates and policies, but it is not their main role. Nominating candidates remains a fundamental responsibility of political parties in the electoral process.

I hope this explanation clarifies the main role of political parties in nominating candidates. Let me know if you have any more questions!
