Samuel Goldman, assistant professor of political science at George Washington University, states that
Sanders' platform is not socialist and is better described as "welfarism" reminiscent of the 1950s that aims to regulate rather than to replace capitalism. Goldman notes that Sanders does not advocate public ownership of the means of production nor does he seek to abolish the profit system, both of which Goldman considers to be defining characteristics of socialism.[10]
Lane Kenworthy, professor of sociology at the University of California at San Diego, has stated that Sanders is a social democrat and not a democratic socialist, and that the two ideologies are fundamentally different from each other. Kenworthy points out that social democracy does not aim to abolish capitalism, and argues that Sanders' use of the term "socialism" when he actually advocates "social democracy" is causing more confusion than it is adding value, and might unnecessarily have a negative impact on his presidential campaign. Mike Konczal, an economic policy expert at the Roosevelt Institute, also characterizes Sanders' positions as "social democracy" rather than "socialist", noting that social democracy means support for a mixed economy combining private enterprise with government spending, social insurance programs, Keynesian macroeconomic policies, and democratic participation in government and the workplace—all of which are a part of Sanders' platform.[11]
Andrei Markovits, professor of political science at the University of Michigan, defines democratic socialism as "an attempt to create a property-free, socialist society" and something that does not exist in Denmark or anywhere else in the world, and argues that Sanders' explanation of the term is inaccurate.[12]
