Political ideology refers to a set of beliefs about governance and the role of government in society. It influences policy decisions by shaping how individuals and parties approach issues such as healthcare, education, and economic regulation. For instance, liberal ideologies may advocate for expanded social programs, whereas conservative ideologies may prioritize limited government and free markets. Ideologies serve as frameworks guiding politicians' decisions and electoral platforms. Understanding political ideologies is crucial for analyzing behavior in politics, as they directly impact legislative outcomes and citizen engagement.
