Which of the following is NOT a main objective of political parties?

Political parties have several key objectives that define their role within a political system. Winning elections is a primary goal, as this allows parties to gain power and implement their policies. Influencing government policy is another crucial objective, as parties seek to shape legislation and governance according to their platforms. Additionally, parties aim to form or shape public opinion; they engage in campaigns and outreach to garner support and educate citizens about their positions and values.

The option regarding controlling the judiciary stands out as it does not align with the fundamental aims of political parties. Political parties typically do not directly control the judiciary; rather, they may influence judicial appointments or advocate for certain legal frameworks within the bounds of law and democracy. However, maintaining the independence of the judiciary is essential for a fair political system, and parties do not have a primary objective that involves direct control over judicial matters. This distinction highlights why controlling the judiciary is not considered a main objective of political parties.
