I’m not saying the article doesn’t make some good points. But, much of it is self-contradictory. It says in the beginning of the article that we can rule out progressive appeals to voters as it was the more moderate voters that stayed home. By the end of the article its saying democrats need to appeal to voters by telling them how they will materially improve the lives of working people.

Focusing on how politics can improve lives of working people materially is literally a progressive appeal.
