Answer:
Liberal: Bernie Sanders
Conservative: George W. Bush
Libertarian: Gary Johnson
communitarian: Giulio Andreotti
Step-by-step explanation:
Political liberalism is one that is centered on the principles of political, commercial and social freedom, establishing equality for all before the law. It is right for liberals that the government and political philosophies support the free market, limited government, freedom of the press and religion, free trade, capitalism, individual rights and secularism.
Conservatism defends that government policies are based on traditional institutions of building society, maintaining traditions and defending policies that encourage hierarchy, property rights, organic society, among others.
Libertarianism is the political philosophy that defends freedom as the main engine of society. For them, freedom is a fundamental principle and must be present in politics in a comprehensive way, defending individualism, freedom of choice, voluntary associations and the full economy.
Communitarians are a group of politicians and philosophers who govern the liberal concepts of justice, as they do not believe that they represent the community as it should be defended. This political aspect is extremely centrist and has a strong leftist bias in relation to the economy and conservatism.
