I am specific enough for people who have a reasonable understanding of current colloquialisms. "Progressive" in the context of American politics has a pretty standard meaning, it's just one that I wouldn't call "progressive" in a societal sense. Similar for "conservative" etc. I think if you use context clues it makes modern political jargon more understandable, especially if you discard any expectation that the label is connected to the definition of the word in a general context.
