I'm curious to know why you think it's the artist role to be the political heavy and fix the world's problems when a majority of its leaders can't even get it right, let alone stomach sitting down together. Along with the rest of us, generally speaking who vote and aren't particularly, politically conscious nor active - the exception to the rule are the slurry of "political" blogs whose bark is worse than their bite. But even if Cameron wanted to be political - and I don't think he does, I definitely saw the opposite in the work shown - isn't the real problem that we're trying to be political in an arena or gallery "system" that is not conducive nor interested in such political behavior. It's about the $green$ and nothing else. How can you remain credible in a gallery system that is as politically bankrupt as the "Man" its trying to fight against or change? And finally as Ewa Kuryluk argues in her essay, "A Plea for Responsibility," the only responsibility an artist has is to fight for his/her autonomy to explore and express whatever they find important or interesting.
