I don't understand how this could surprise anyone.
"Creative" people (artists, musicians, actors, directors, etc.), by definition, tend to "live in their own world." They are exactly the type of people who would be attracted to the propaganda of the liberals.
Remember: the message of the liberals is "We'll fix all of the bad things in the world, so that you won't have to feel bad anymore." Of course, there's little mention of HOW they might do this, and they certainly don't take human nature in to any account, nor personal responsibility. But it *sounds* good, and the emotionally-driven suck it right up.
The music and movie industries are NOT representative of average America. They are NOT split 50/50 Dems & Repubs. People in that circle are more like 97+% Dems and 2-3% Repubs. You should ALWAYS keep this in mind anytime those folks are involved with anything even remotely political.
