In addition to a primary, political parties can nominate candidates for general election through a petition or a vote of party leaders. caucus or a convention. signature drive or a public rally. referendum or a ballot initiative.

The main other way, rather than a primary, is a caucus, which is held during a nominating convention ( so the correct answer is:"caucus or a convention"). A primary is a state-wide vote while the caucus is limited to the members of the party and only the people participating the caucus are invited to vote

Idisagree because it would have harmed our whole society. starting from the madness of the civilians to the mass destruction of towns.
