I use the term "Progressive" as a synonym for the political mentality also known as "liberal." There is a big difference between Mr. Quarter and that side of the fence. I found this quote which I think really expresses the "progressive" mentality:
"Progressives believe that the top priority of politics should be more equitable government distribution of opportunities and goods."
On the other hand, as a "Conservative", I believe in the centrality of individual freedom, protection and preservation of religion and morality, limiting government’s scope, preservation of the free-market as the basis for economic activity, and ensuring that the principles embodied in the Declaration of Independence and the Constitution are the only ones that guide our government.
