Supporters of Sanders, on the whole, were not to the left of supporters of Clinton on policy. Instead, there was something more presentational about the divide — how they chose to express belief more than belief itself, a feeling about how policy should be discussed and in what terms.
Perhaps for that reason, the generational difference in ideology seems not to have translated into more liberal positions on concrete policy issues — even on the specific issues championed by Mr. Sanders. For example, young Democrats were less likely than older Democrats to support increased government funding of health care, substantially less likely to favor a higher minimum wage and less likely to support expanding government services. Their distinctive liberalism is mostly a matter of adopting campaign labels, not policy preferences. (Source)
