I heard Bill Maher use this term on Fresh Air. You'll have to listen to it yourself to see how he uses it.
To me, it means the large number of people who want to feel that they are part of the political process by having an opinion about a political issue, but have not actually bothered with the hard work it would take to determine the facts behind the issue. Rather, they seize the opinion of a celebrity (which could mean actors, sports figures, politicians, comedians, etc.) and represent it as their own.
These are the people who believe that all or most problems could be solved by applying their demagoguery wholesale.
I, on the other hand, subscribe to the notion that the world is best served by simultaneously serving both sides of a paradox. More on this later, when I can better think of a fine way to illustrate what I mean.
