Political ideologies shape party positions on key issues in the United States. Liberals champion individual rights, social welfare, and environmental protection, while conservatives advocate limited government, free markets, and traditional values.

These ideological differences impact policy debates on economics, healthcare, environment, gun control, and immigration. The growing polarization between liberals and conservatives has led to increased partisanship, media fragmentation, and gridlock in policymaking.
