The left needs to make it clear what values we stand for. As examples:

+ Decreasing the wealth gap;

+ Health care as a right not a privilege;

+ Preservation of the commons;

+ Rights of real persons supersede rights of corporate "persons;"

+ Mass media distribution networks are public not private (electromagnetic and satellite spectra, natural monopoly cable networks)

+ Democratic freedoms and decisions supersede economic freedoms;

+ The environment and natural living resources have rights that must be protected at the constitutional level;

Add more basic "values" in the comments below.
