Are artists inherently liberal or conservative?

The general belief is that artists are all liberals, one only has to look at the fact that all of Hollywood was behind John Kerry in 2004. But here is a provacative arguement that they are inherently conservative. I don't agree (because of matters of what a conservative and liberal are), but it seems worth pondering (this is via so many sources, just go here and find out where the root is yourself):

To be a great artist is inherently right wing. A great artist like Dylan or Picasso may have some superficial, naive, lefty things to say, but underneath, where it counts, there is a strong individual, taking responsibility for his place in the world and focusing on that.
