Liberalism typically advocates for social equality, environmental protection, and government intervention in the economy, while conservatism emphasizes tradition, limited government, and free-market principles. These ideologies guide party platforms, policy debates, and voter behavior, influencing the political landscape. Understanding them aids citizens in making informed choices and fosters constructive political discourse, essential for a thriving democracy.
