Why are so many recording artists liberal democrats?

I see that Ann and Nancy Wilson of Heart are upset about McCain %26amp; Palin using ';Barracuda'; during the GOP convention and asked them to stop using it immediately. Aside from some country western stars, it seems as if most popular music artists are vocally left-wing, similar to actors I guess. I wonder why that is the case?

I have a few opinions in this matter. Musicians tend to try to appeal to the masses in order to promote their art... if their ';message'; was that of being from a higher tax bracket (of which they become once their music sells) who would buy their CDs?





Also, artsy folks are thought of the type that give more back to those in need, which the Democrats taut as their message.





Realistically, Republicans do give more back but not generally as a physical act but as a monetary act. And when they do donate money it's a substantial difference compared to their cheaper Democratic counterpart.





Bottom line... most music has been about pain and suffering which seems to be the way Democrats want the world to view itself as. When McCain and Palin have a message of hope, which artist wants to be associated with that if it doesn't sell records???!!!Why are so many recording artists liberal democrats?
Well, suffice to say there aren't many ';intelligent'; celebrities in the world, so I suppose there's your answer.
Who knows. I just pick the lesser of the two problems, and of course my pick is Obama.
It is a result of their high intelligence.
