As the public begins to realized that the "New and Improved" is just the same old thing, these terms will be changed once again.

Actually, they called themselves "Progressives" first, during the last half of the 19th century and early 20th century. You may recall that Teddy Roosevelt's "Bull Moose" Party was actually named the Progressive Party.
It was only when a short-lived reaction against Progressivism came in during the 1920's that they started calling themselves "Liberals," in an effort to suggest that they were in line with liberal thinking of America's founders, who were (and still are) known as Classical Liberals. Now that Liberal has come to be associated with the failed policies of the left, they are re-adopting the term "Progressive" in a slimy attempt to continue their hallowed tradition of hiding their true social engineering nature.
