Hence they use the nondescript term, "progressive", which can mean anything to anybody. Personally I think conservatism is progressive because it's the best way for the nation to go. To be more specific liberal talk radio should probably call itself socialist talk radio.
Dig a little deeper into history. Go back 100 to 120 years ago and focus on the Midwestern area anchored by Minnesota and Wisconsin. I think you will find "progressive"
anything but nondescript. A number of things that you take for granted in your socio-political being have their roots in actions fought for by The Progressive Party people of that area.
That does not mean you will suddenly like those results thrust into your life by The Progressives, but it does mean "nondescript" probably doesn't work very well in this conversation.
Now, bringing all that back to radio: Liberal radio, Progressive radio, whatever it should eventually be called needs to quit letting Conservative radio be of official "namer" of all the animals in creation to borrow from the Adam and Even Saga. Conservative radio put much energy in deciding who will be called what... and too much of the effort to be "alternative" political expression (not conservative) goes on stage and acts out the script written for them by Conservative Radio.
It is possible that progressive/liberal radio will eventually grow up and discover it's very own persona and then our country will be blessed with authentic, self-policing and correcting, two-way conversation that has been a part of our heritage for over two centuries.
A historical post-script here:
You'll find that religion was a critical component in a number of 19th century movements: anti-slavery, suffrage, charity, supporting the poor, pro-union, humanized treatment of the mentally ill and prisoners. People like Elizabeth Cady Stanton, Susan B Anthony, John Brown, General William Booth (who founded the Salvation Army). During the reconstruction era, these particular religionists came to be known as Christian Progressives. The roots of this progressive Christianity can be traced back certainly to our American roots in France, the Enlightenment Period and the notion of individual liberty --pluribus, if you will-- but the efforts of Christian progressives along with many social progressives who fought for reforms, led to numerous social changes of which we are familiar (I presume) coupled with political realities like Interstate Commerce Act, the Sherman Antitrust Act, direct primary, secret ballot, and the initiative, referendum and recall. Teddy Roosevelt's presidency was a direct manifestation of these various dynamics.
