Often considered one of the most popular politicians in America, Sanders self-identifies as a democratic socialist and has been credited with influencing a leftward shift in the Democratic Party since his 2016 presidential campaign. An advocate of social democratic and progressive policies, he is known for his opposition to economic inequality and neoliberalism. On domestic policy, he supports labor rights, universal and single-payer healthcare, paid parental leave, tuition-free tertiary education, and an ambitious Green New Deal to create jobs addressing climate change. On foreign policy, he supports reducing military spending, pursuing more diplomacy and international cooperation, and putting greater emphasis on labor rights and environmental concerns when negotiating international trade agreements. Sanders supports workplace democracy, and has praised elements of the Nordic model. Some commentators have described his politics as aligned with the New Deal policies of President Franklin D. Roosevelt and left-wing populism.
