A progressive is a new name for a liberal, or at least it ought to be. In the last few years, the term liberal has been badly villified. As far as I am concerned (labels aside), we 'progressives' care about issues like health care, social security, constitutional and civil rights. These issues should be paramount to EVERYONE. We have simply switched labels for the sake of stepping away from a villians label.
