What is the difference between the terms "liberal" and "progressive" in American politics?

[woo me with science]

46. Corporatists are busy with propaganda to try

to recast everything formerly understood to be liberal and progressive as "fringe." Meanwhile, they describe themselves as proud liberal or centrist Democrats while espousing policies that are not even moderate, but extreme corporatist and right-wing.

Indefinite detention, "kill lists" and drone wars, pre-emptive war as administration doctrine, spy centers for mining or surveillance of all phone calls and email without a warrant, internet IDs and internet-censoring measures like ACTA, military drones in American skies, coordinated violent crackdowns against peaceful protesters, strip searches for any arrestee, bailouts and settlements for corrupt banks, and austerity budgets in an economy that has already impoverished its middle class.....

These are not moderate or centrist positions. Not by a long shot.

They are extreme corporatist, neocon, and police state policies, not "centrist" or moderate at all. And they are minimized, rationalized or even defended every day here by Third Way posters who claim to be liberals.
