This design features the election symbol of the U.S. Libertarian Party. The logo is in the public domain. The party generally promotes a classical liberal platform, in contrast to the Democratic Party's modern liberalism and progressivism and the Republican Party's conservatism. Current fiscal policy positions include lowering taxes, abolishing the Internal Revenue Service (IRS), decreasing the national debt, allowing people to opt out of Social Security and eliminating the welfare state, in part by utilizing private charities. Current cultural policy positions include ending the prohibition of illegal drugs, advocating criminal justice reform, supporting same-sex marriage, ending capital punishment and supporting gun ownership rights. It is currently the third largest political party in the United States by voter registration. The porcupine is used as a symbol of libertarianism because it is a defensive animal that doesn't harm anyone who leaves it alone.
