If you really think about it, I can’t think of two “jobs” that are more interconnected. Politics and art are, essentially the same thing. Let me explain myself.
What is art? What does it try to do? Art is a means in which a person expresses their feelings about the world around them. It could be something as simple as a beautiful postcard with the Hawaiian islands on it. The artist is trying to show you that Hawaii is a great place to vacation. The more complex you get, it’s still all the same. If the artist thinks their government is unfair, they might paint their president in a less than flattering light. Either way, the artists job is to express themselves in a way that impacts the world around them, so if they, for example, hate president Bush, they might make a song about how much he sucks (or sucked, for that matter) or paint a picture of him looking more like a money than he already does. The artist will try to impart their beliefs onto their audience. That is the whole point of art. It’s not to make money, that would be a bad reason to get into the art community. It’s not merely to express oneself, you could just do that in private and just expressing yourself is a lot like, and I’m going to quote Dennis from It’s Always Sunny in Philadelphia,
“It is like flipping through a stack of photographs. If I’m not in any of them and nobody is having sex, I just don’t care.”
If you are making art merely for self expression, it’s not going to affect (or is it ‘effect’? I never know) anyone but the artist. The point of art is the change the world by changing the minds of other people. That is what an artist should be striving for.
A politician does the same thing. Whether or not a politician believes in what he/she is saying or promising, that politician is going to do their best to change the mind of the voters to be on their side. A politician would never just run for President because they feel like it. No, they do it because they feel the need to change their community. It’s for the best of the people (or at least, it should be).
Basically, politicians and artists are in the same business- changing their world for the better.
