I think that’s true and certainly resonates with own experiences running a field office last cycle. The “consequences of policy” arguments are winning ones for progressives. I’m a fan of the Public Leadership Institute’s guide to talking about issues — that broadly applies to campaigning, too, in that progressives need to make it clear that they’re not just better than their opponents, but that they’re offering a program that will directly and constructively benefit workers and the middle class. Importantly, succeeding with that message requires acknowledging the need to change the power relationships in our society. For Democrats, that means embracing more Sanders-style and, honestly, FDR-style populism.
