Political ideology significantly affects policymaking by shaping the values and priorities of political leaders and parties. For instance, conservative ideologies may emphasize free markets and limited government intervention, leading to policies that prioritize tax cuts and deregulation. Conversely, progressive ideologies often focus on social justice and environmental protection, resulting in policies like universal healthcare and stricter regulations. The dominant ideology can influence public opinion, party platforms, and the legislative agenda, ultimately determining the direction and effectiveness of governance in a state.
