definition of political class? please help!?

It is almost always used as a synonym for 'ruling class'. In the U.S. it would include career politicians as well as those who get them elected.

I'm trying to find the answer to the exact same question actually. I *think* "political class" refers to people who consider themselves Democrats or Republicans rather than being more independent-minded. I could be wrong though, but that's about the closest I've been able to come to a definition.
