Steyer is jettisoning the concept of persuading voters and arguing for winning through turnout. We recently talked to Nate Cohn about this on the FiveThirtyEight Politics podcast, but according to the data, there is no good reason to believe that turning out low-propensity voters or nonvoters will necessarily help Democrats. It's highly dependent on where in the country we are talking about, and high turnout inn the Midwest could actually hurt Democrats.
