What Is the Democratic Party's Position on Filling the Blank?

There is no cogent, visible left wing answer alternative that we have been able to present us thus far. Burney sanders started to do that in articulate and chart a different vision of what that could look like. And i don't think anybody on his team could even give us a straight answer, because never thought about it. It's a very real, a very live question to me,. What ultimately is going to be in the democratic establishment, such as it is, in its weak, desicated state?
